TSA Officers Focus on Security, not Good Looks

The internet is abuzz with posts, tweets and news articles regarding allegations that TSA officers required a passenger to go through a body scanner multiple times because she was attractive.

First, I want to reassure all passengers that TSA does not profile passengers.   

Second, I’m pleased to inform all concerned parties that every single one of our millimeter wave units in the field, including those at Dallas/Ft. Worth (DFW airport), have been equipped for quite some time with privacy software that no longer displays a specific image of the person being screened.

The monitor is mounted on the scanner itself, and here’s what both the passenger and officer see:

That’s it. In fact, if there are no alarms, a green screen with “OK” is all that’s displayed. There is no longer a need for an officer to review images in a remote location because there are no longer any privacy concerns with the image. 

Even when we did review the images in a remote room, they looked more like fuzzy photo negatives than the images that some make them out to be. Furthermore, it’s not TSA’s policy to scan passengers multiple times. 

We have no record of the passenger filing a complaint when this allegedly occurred more than six months ago. Had it been reported to TSA at that time, we could have reviewed CCTV and interviewed the officers. We were instead notified about these allegations by the media more than six months after the alleged incident. 

In situations such as these, passengers should use Talk to TSA to contact a customer support manager at the airport they traveled through. Passengers can also call our contact center. We want to hear from you, good or bad. We take your feedback seriously and will use the details you provide to look into your concerns. 

Our backscatter units (another type of body scanner) will eventually use the same software and still required the need of an officer in a remote private location to view the images. That officer never sees the passenger, just their image. In case you’re wondering, DFW only has millimeter wave units.

When it all comes down to it, our officers are focusing on keeping passengers safe, not their good looks.

The Truth About TSA Testing Technology for Radiation

Unfortunately, yesterday’s LA Times story missed the mark and you may have seen a few additional inaccurate stories in the news claiming that TSA was buying equipment to test for radiation exposure. Truth is, we continuously test all of the technology we use and post the results to our website for all to see.

Why the confusion you might ask? TSA routinely puts out Requests for Information (RFI) that are basically market research, asking industry to tell us what else is out there. In this case, TSA put out an RFI to gather information on available tools to continue to monitor our technologies. This is simply designed to ask industry what new technology might be available.

Testing our equipment and exposure to employees is not new. TSA routinely monitors radiation levels to ensure the safety of both passengers and our workforce. We've never found any radiation concerns and the safety reports can be accessed publicly at TSA.gov. TSA made a commitment to post new reports as they're completed to our website so passengers can see for themselves that the machines are meeting safety standards.

Based on all of our previous testing, as well as monitoring from independent sources, we’re confident that all of our equipment meets national safety standards, and is safe for all passengers and our workforce.

As far as another backscatter (body scanner) test is concerned, TSA is committed to working with Congress to explore options for an additional study to further prove these machines are safe. All tests so far, have shown they are well within the national safety standards and each scan is equivalent to the exposure one receives during approximately 2 min of flight.

In Case You Were Wondering, Our Backscatter Imaging Technology Is Still Safe

The safety of our Backscatter Advanced Imaging Technology is being called in to question again. As I’ve done before on this topic, I’m going to simply provide a bulleted list of facts and links. Also, if you haven’t heard yet, TSA Administrator John S. Pistole told Congress last week that we’re going to have another independent safety study on our Backscatter imaging technology.

The Johns Hopkins University Applied Physics Lab (APL) and the Food and Drug Administration (FDA)’s Center of Devices and Radiological Health (CDRH) both verified that the advanced imaging technology (AIT) equipment TSA purchased and deployed emits radiation at rates much lower than the limits set in the national radiation safety standard for all members of the traveling public and all TSA employees.  

The Johns Hopkins University Applied Physics Lab assessment included several recommendations to continue to ensure the highest standard of safety and health. TSA has successfully completed each recommendation.  
A backscatter scan is equivalent to amount of naturally occurring radiation received during two minutes of flying at altitude.  

In addition to these independent studies validating the safety of imaging technology, TSA also conducts site acceptance testing of AIT units upon installation in airports to ensure each individual AIT unit meets safety standards.  Once installed, preventive maintenance is regularly performed by qualified personnel.  

Certified health physicists from the U.S. Army Public Health Command are also performing additional radiation safety surveys to ensure continued compliance with radiation safety standards.  

In early 2011, TSA posted radiation surveys for every backscatter imaging technology unit deployed in U.S. airports. The reports confirm that every backscatter unit currently used for passenger screening in U.S. airports is operating well within applicable national safety standards.  

TSAposts reports for all radiation tests, including the annual TSA-mandated testof every X-ray based technology, on TSA’s website as they are completed.  

Accordingto CBS News, MIT’s leading radiation safety experts and experts from the HealthPhysics Society, drinking three glasses of water a day for a year might giveyou a cumulative exposure of about 0.045 millirems, that's at least five timesmore than the dose from an airport scanner and well beneath the 10,000 milliremline where there is danger. According to Francis Marre, former director ofradiation safety at MIT, “There is no known risk” from being scanned.

HealthPhysics Society’s FAQ: “ Safety for Security Screening Using Devices ThatExpose Individuals to Ionizing Radiation.  

FDA FAQ page: “Products for Security Screening of People”.  

SFWeekly article featuring leading radiologists refuting safety claims by UCSFprofessors.  

National standard for one backscatter scan: 0.025 millirem (two and a half one-hundreths of a millirem) per scan.  

TSA’s backscatter systems maximum possible radiation emission: 0.005 millirem (five one-thousandths of a millirem) scan.  

TSA’s backscatter systems actual emission: generally less than 0.0025 millirem (two and a half one-thousandths of a millirem) per scan.  

Advanced imaging technology screening is safe for passengers, including pregnant women and children. One backscatter technology scan produces the same exposure as approximately two minutes of flying on an airplane. Advanced imaging technology is optional for all passengers.

TSA Takes Further Steps to Enhance Passenger Privacy on Millimeter Wave Machines Nationwide

Back in February, I posted about how we had begun testing Automated Target Recognition (ATR) software for millimeter wave Advanced Imaging Technology (AIT).  The testing started at the Transportation Security Lab (TSL) back in the fall of 2010, and after piloting the software in the field (ATL, DCA, and LAS) we’re ready to start rolling it out!

Over the next few months, the software will be installed on every millimeter wave imaging technology unit in the field.  Future millimeter wave units will come with the new software already installed.  There are currently nearly 500 AIT units in the field (both backscatter and millimeter wave), and there are plans to roll out even more later this year. As far as backscatter units, there are plans to test similar software in the fall.

If you’re not familiar with ATR, it works with our imaging technology (Body Scanners) and eliminates passenger-specific images and replaces them with the generic outline of a person.  Here’s how it works: You step into the AIT machine and the new software will auto-detect potential threats and show their location. The image is on a monitor that is attached to the AIT unit in public view. Because this eliminates privacy concerns, we no longer have to place an officer in a separate room to view the images. 

Alarm image:

If there is no alarm, the following is displayed:

We are always looking for new technology and procedures that will both enhance security while strengthening privacy protections. That’s why we worked with the Department of Homeland Security’s (DHS) Science & Technology Directorate (S&T) and private industry to develop the software.

TSA Cancer Cluster Myth Buster

This is old news, but it’s back in the news and since it’s such an important topic, we wanted to address it again to alleviate any concerns it might be causing.

Myth: There is a TSA employee cancer cluster at the Boston Logan International Airport (BOS) related to the backscatter body scanners.

Fact:  There is no relationship between any cancer diagnoses in Boston and the technology in the airport. (Based on a survey by the National Institute for Occupational Safety and Health). In fact, there were no body scanners at BOS when the complaints were filed.

I blogged about this back in May, but all of our X-ray technology (backscatter body scanners, and all baggage scanners) has been tested and retested and our scanners are operating safely. You can actually take a look at the reports and read about how we test the machines here. 

Common Questions: 

Q: Why aren’t your officers permitted to wear dosimeters? 

 

A: There is a really good reason for this. The emissions from our X-ray technology are well below the requirements that would require their routine usage. To  help reassure passengers and employees that the technology is safe, however, health physicists with the U.S. Army have been conducting area dosimeter surveys at multiple airports nationwide.

Q: Why doesn’t TSA allow third party testing for the backscatter technology?

A: We have. Independent third party testing and analyses of TSA backscatter technology have been conducted by the U.S. Army Public Health Command, the Food and Drug Administration’s (FDA) Center for Devices and Radiological Health (CDRH), the National Institute of Standards and Technology (NIST), and the Johns Hopkins University Applied Physics Laboratory (APL). They all came to the same conclusion by the way. It’s safe…

Archives of Internal Medicine on TSA Backscatter: “There is no significant threat of radiation from the scans.”

It’s no secret that Advanced Imaging Technology (AIT) has been a hot topic ever since we first wrote about in 2008. While we’ve posted many times on the subject, readers often want to hear from independent third parties to see what their take is. That’s understandable.  So, as we’ve  done in the past, we’re going to highlight another piece on backscatter safety from a third party.

This report comes to you from the Archives of Internal Medicine. In the report, they conclude that there is no significant risk from the radiation emitted during the scans. You can read the full report here:

Facts on TSA X-ray Safety

The Transportation Security Administration (TSA) uses X-ray technology on people and baggage daily in an effort to find items that could cause catastrophic damage to an aircraft. Some are asking how safe this technology is how and how we maintain it to ensure there is no excessive radiation exposure for workers or the traveling public. So, I’d like to use this post to address those questions with facts provided by TSA’s director of occupational safety, health and environment, Jill Segraves. 

·     Before TSA decides to use a new technology, procurement specifications are developed that include requirements to meet the national radiation safety standard. The requirements are validated by manufacturers through third party testing or through testing arranged by TSA, to ensure it meets national safety standards. 

·     After deciding to use new technology that has proven to be safe and meets applicable standards, the manufacturer then will conduct validation tests on each individual unit in the factory during their quality assurance process before the unit is shipped to TSA. 

·     For the carry-on and checked baggage x-ray systems and the general-use backscatter advanced imaging technology equipment, the factory tests, post-installation tests and regular preventive maintenance mentioned above all include radiation safety surveys.  These surveys verify that each unit operates within specifications, is installed correctly and continues operating according to specifications for the life of the unit. When the technology operates as designed, the dose to any member of the general public, system operators, or other employees falls well below the national standard for safety.  

·     The regular preventive maintenance checks, including radiation safety surveys, are performed at least once every 12 months; after any maintenance that affects the radiation shielding, shutter mechanism, or x-ray production components; after any incident that may have damaged the system; after a system is moved or at the request of any employee. 

·     In addition, TSA partnered with the U.S. Army Public Health Command (Provisional) to conduct independent radiation surveys and inspections to confirm the regular testing performed by TSA. Health Physicists from the the U.S. Army Public Health Command (Provisional) perform the surveys and inspections. 

·     The Public Health Command’s Health Physicists also check the indicators, controls, labeling, and observe system operators to ensure proper operating procedures are followed.  The Health Physicists are also gathering area radiation dose data by mounting dosimeters within the inspection zone (that area only occupied by the individual undergoing the screening and delineated by the yellow bordered floor mat) on  certain equipment. 

·     Over the past two years, Health Physicists performed radiation surveys and inspections of 437 carry-on luggage and checked baggage systems at 34 airports during screening operations, and observed system operation and work practices.  The Health Physicists work has thus far confirmed TSA testing that shows all of these systems operating well within safety standards.

·     On top of all these steps, more than 1,100 TSOs at six airports have participated in a mandatory personal radiation dosimetry study over the past year.  The results of both the dosimetry study and other surveys to date reveal that TSA systems are in compliance with safety standards.

On a related note, a study conducted by the National Institute for Occupational Safety and Health (NIOSH) at the Centers for Disease Control just a year after TSA was stood up in the aftermath of 9/11 (between August 2003 and August 2004) has been getting some attention recently. The study came about after TSA requested it when management and other employees expressed concerns about their safety on the job. NIOSH looked at the levels of radiation emissions from Explosives Detection Systems (EDS) and evaluated employee exposure to radiation at airports during baggage screening.

Transportation Security Officers (TSOs) from 12 airports were highly engaged in this study. They chose the airports to include in the study, provided valuable input, and assisted the NIOSH researchers during the on-site surveys. The report was released on October 1, 2008. You can read the report here.  NIOSH made several recommendations that TSA has since implemented.

Some of the information below duplicates some of the information I mentioned previously but I am including it here to show steps taken since the completion of the study in 2004:

·     TSA has implemented key recommendations from NIOSH, including formalizing a comprehensive radiation safety program to meet OSHA and Department of Homeland Security (DHS) requirements and evaluating TSO radiation exposure levels at selected airports through an additional year-long dosimetry study that commenced in April 2009.

·     TSA took additional steps to ensure safe working conditions for our workforce, including:

·     Adding EDS safety training to baggage screening courses;

·     Increasing the number of service technicians equipped with radiation survey meters;

·     Improving maintenance through more stringent maintenance contracts;

·     Working with EDS manufacturers to improve machine design;

·     Providing annual radiation safety awareness training for all TSOs; and

·     Using Safety Action Teams, Collateral Duty Safety Officers (CDSOs), and Employee Councils to improve health and safety communications between employees and management.

·     Consistent with the recommendations of NIOSH, each piece of TSA equipment that uses ionizing radiation undergoes an initial radiation survey upon installation and an annual radiation survey to ensure it stays in top working condition.  In addition, radiation surveys are performed after maintenance on components that affect radiation safety and at the request of employees. This provides a continuous level of safety.

·     Over the past two years, Health Physicists from the U.S. Army Public Health Command (Provisional) performed radiation surveys and inspections of 437 (carry-on luggage and checked baggage systems) at 34 airports during screening operations while items were entering and exiting systems with the leaded curtains constantly in motion.   The Health Physicists also observed system operation and safe work practices.  Over the past year, more than 1,100 TSOs at six airports have participated in a mandatory personal radiation dosimetry study.  The results of both the dosimetry study and surveys to date reveal that TSA systems are in compliance with the Food and Drug Administration’s standard for cabinet x-ray systems emission limits.

This is a lot of information to read through, but after reading, I’m sure you’ll find that TSA is doing its part to ensure the safety of its employees and the traveling public.

TSA Purchases Additional Advanced Imaging Technology Units (And a Quick Word on Automated Target Recognition)

Why did TSA decide to use backscatter instead of millimeter wave advanced imaging technology (AIT)?

This is a question we’ve been getting a lot lately. The truth is we didn’t choose one over the other. We’re currently using both backscatter and millimeter wave technology, and we just announced that we purchased 302 additional imaging technology units. We are buying 202 millimeter wave units  and 100 backscatter units.

In order to be included in the competitive process, strict detection standards must be met. Currently, only two companies have AIT machines that meet those standards. As companies develop new über cool technologies, they can be included in the competitive process.

Speaking of fantabulous über cool technologies, many have also asked why we’re not using Automated Target Recognition (ATR) software since the technology exists. ATR software is used with AIT and displays a generic stick figure-like image on the monitor attached to the AIT machine to show potential threats concealed on a passenger, and does not display the actual image of the passenger. It provides stronger privacy protections and eliminates the need to staff an extra officer in a private room. We’re very interested in this next generation software, but ATR in its current form does not meet TSA’s detection standards.

Software development is currently underway and will be followed by testing to ensure it meets our detection standards.

We’ve posted many times on AIT. You can read much more about it here on our blog, or at TSA.gov.

Advanced Imaging Technology Off To a Great Start

Since 2009, officers operating advanced imaging technology (AKA “body scanners”) have found all sorts of things on passengers. Some of these items have been smaller items such as a three inch pocket knife hidden on someone’s back, little packets of powder, a syringe full of liquid hidden in someone’s underwear, and other small items either intentionally hidden or forgotten. These finds demonstrate that imaging technology is very effective at detecting anomalies and can help TSA detect evolving threats to keep our skies safe.

Some might wonder what kind of damage small items could do to a plane since we’re looking for threats such as explosives. At first thought, you would probably think “not much,” but in addition to explosives, we’re also looking for bomb components, among other threat items. There’s more to a bomb than the explosive (timers, initiators, switches, power sources, etc.).


Since our machines can detect such small items, I feel it’s important to remind passengers that when going through AIT screening, be sure to take everything out of your jacket, pants and shirt pockets. And unlike before with the walk through metal detector (magnetometer), wallets and other stuff you didn’t need to take out before will have to come out so we can get a clean image. And that goes to the folks who tuck stuff in their socks too. Making sure you get all the items out of your pockets will get you through the machine much more quickly without secondary screening and will allow the lines to move faster.

This post highlights that AIT is detecting potential threat items concealed under clothing and its deployment is helping to keep travelers safe by improving security at our airports.

As of yesterday, Charlotte Douglas International Airport is the latest airport to roll out Advanced Imaging Technology.

We’ve talked about this technology on the blog many times and you can read all of the AIT related posts here.

***Update - 4/21/2010***

We wanted to clarify that the ceramic knife in the image used for this post was discovered during the pat down of a passenger who opted out of AIT.

Advanced Imaging Technology: "Radiation Risk Tiny"

You may have read a recent article stating that Advanced Imaging Technology used at TSA checkpoints is not safe. Because of the discussion the article has created, I wanted to share this with you.

The American College of Radiology posted an article titled: ACR Statement on Airport Full-body Scanners and Radiation and then WebMD followed up with an article titled New Airport Scanners: Radiation Risk Tiny which quoted the ACR article.

From the ACR article: "An airline passenger flying cross-country is exposed to more radiation from the flight than from screening by one of these devices. The National Council on Radiation Protection and Measurement (NCRP) has reported that a traveler would need to experience 100 backscatter scans per year to reach what they classify as a Negligible Individual Dose. The American College of Radiology (ACR) agrees with this conclusion. By these measurements, a traveler would require more than 1,000 such scans in a year to reach the effective dose equal to one standard chest x-ray."

"The ACR is not aware of any evidence that either of the scanning technologies that the TSA is considering would present significant biological effects for passengers screened."

We also asked the Johns Hopkins University of Applied Physics Laboratory to perform an independent radiation safety engineering assessment of our Advanced Imaging Backscatter Technology and they determined that the radiation dose to scanned individuals from this general use system is within the requirements of ANSI N43.17 2002 and 2009.

In the coming weeks, the FDA will be posting similar information on their web page.

For your reference:

Backscatter technology projects an ionizing X-ray beam over the body surface at high speed. The reflection, or "backscatter," of the beam is detected, digitized and displayed on a monitor. Each full body scan produces less than 10 microrem of emission, the equivalent to the exposure each person receives in about 2 minutes of airplane flight at altitude. It produces an image that resembles a chalk-etching.

Millimeter wave technology bounces harmless electromagnetic waves off of the human body to create a black and white image (not a photograph). It is safe, and the energy emitted by millimeter wave technology is the energy projected by the system is thousands of times less intense than a cell phone transmission. This technology is not new. TSA is not the first to use this technology. It's currently being used in Canadian airports and U.S. courthouses in Colorado and Texas as well as international locations.

This Standard limits the reference effective dose2 delivered to the subject to 0.25 microsieverts (25 microrem) per screening.

For your reading pleasure, here are some documents relevant to security screening of humans using ionizing radiation:

ANSI/HPS N43.17-2009 Radiation Safety for Personnel Security Screening Systems Using X-Ray or Gamma Radiation

NCRP commentary 16, Screening of humans for security purposes using ionizing radiation scanning systems

NCRP Statement 10, Recent Applications of the NCRP Public Dose Limit Recommendation for Ionizing Radiation (2004)

NCRP report no. 116 Limitation of Exposure to Ionizing Radiation (1993) ISBN 0-929600-30-4 recommends annual limits on radiation dose for the general public. Report 116 also introduces the concept of a negligible individual dose.

NCRP report no. 160, Ionizing Radiation Exposure of the Population of the United States (2009)

Screening Individuals with Backscatter X-Ray Systems by Daniel Strom

HPS Position Statement Use of Ionizing Radiation for Security Screening Individuals

HPS Public Information Radiation Exposure During Commercial Airline Flights

American College of Radiology (ACR) Statement on Airport Full-body Scanners and Radiation

EPA.gov Ionizing Radiation

Information on laws and regulations applicable to manufacturers of people screening security systems that use x-rays is on FDA's X-Ray & Particulate Products other than Medical Diagnostic or Cabinet page.

ANSI/HPS N43.17 is not a mandatory standard. More information on the ANSI standards setting process is available on the ANSI website.

The concept of justification based on a societal benefit appears in the International Commission on Radiological Protection (ICRP) report 60 (see paragraph S14).

Random Facts:

For comparison, the energy projected by millimeter wave technology is 10,000 times less than a cell phone transmission.

We, and all objects around us, generate millimeter wave energy - and we are exposed to it every single day.

Backscatter technology uses low level X-ray and a single scan is the equivalent of two minutes of flying on an airplane.

Full Body Scanners at Security Okay by Travelers - When it comes to the newest addition to airport security, 79 percent of travelers said they are comfortable with U.S. airports using full body scanners that can see through clothes.

Backscatter Advanced Imaging Technology on Its Way to First Eleven Airports

The first 11 airports receiving advanced imaging technology (AIT) units are gearing up for their arrival.

Advanced imaging technology safely screens passengers for metallic and non-metallic threats, including weapons, explosives and other objects concealed under clothing that might normally go undetected.

AIT units are currently being set up at Boston Logan International airport, and within a week they’ll be at Chicago O’Hare International airport. You should see the rest of the airports on this list in action by this summer:

· Boston Logan International (BOS)
· Charlotte Douglas International (CLT)
· Chicago O’Hare International (ORD)
· Cincinnati/Northern Kentucky International (CVG)
· Fort Lauderdale-Hollywood International (FFL)
· Kansas City International (MCI)
· Los Angeles International (LAX)
· Mineta San José International (SJC)
· Oakland International (OAK)
· Port Columbus International (CMH)
· San Diego International (SAN)

A total of 450 AIT units will be deployed by the end of 2010 and the additional airports will be announced in the near future.

You might be wondering why it takes so long to deploy these machines. Well, it’s not as if you can pop these out of the box and plug them in. Many factors are taken into consideration before AIT units are deployed, including the airports' infrastructure. These machines are big, and don’t forget about the remote viewing location that goes along with the machines. So as you can imagine, there is much planning going on behind the scenes before these machines actually arrive at their airports and are ready to screen.

We’ve posted here on the blog about AIT many times in the past, and here are some links to previous blog posts to help answer some of the questions you might have:

Can your image be saved or printed? No.

What will my image look like? What will TSA officers see? Take a look…

Will children be screened with this new technology? Yes and no.

What’s the difference between millimeter wave and backscatter? Read here...

Has my privacy been taken into consideration? Are these machines safe? Yes.

Currently, 40 AIT units purchased previously are deployed at 19 airports nationwide.

Bollywood Confidential

A rumor is going around that Bollywood superstar Shah Rukh Khan had an Advanced Imaging Technology (AIT) image of himself leaked by UK Security officers at Heathrow. This rumor, though juicy, is unfounded.

TSA reached out to the UK's Department for Transport (DFT) and learned that, just like advanced imaging technology machines in U.S. airports, they do not have printers or the ability to store images in the airport setting.

Additionally, DFT pointed TSA to the source of the rumor: an interview with BBCs Jonathan Ross. Though he doesn't explicitly say that he's joking, we can confirm in all seriousness that the machines don't do what he jokingly describes.

What’s Wrong With This Picture?

What’s wrong with this picture? Put quite simply, it’s a fake. The picture (minus the black boxes) has been gaining popularity ever since it was used on several popular web pages and blogs.

The TSA Office of Information Technology (OIT) was able to determine that the original images used to make these pictures were taken from a stock photo website and doctored to mimic Advanced Imaging Technology (AIT) images. The doctored images are nothing more than full frontal photos (hence the black boxes) with the colors inverted. The image of the gun and belt were superimposed. This can be done with any basic image editing software.

It’s obvious that the woman shown on the left is not the woman in the doctored photos on the right. Notice that the bracelet on the right wrist in the clothed image does not appear in the doctored images. Her arms and legs are also in different positions in the clothed photo. It can be argued that maybe the photo was taken before she entered an AIT machine. Even so, just like X-ray images, hair does not show up in authentic AIT images and faces are blurred with a privacy algorithm.

Please take a look at this blog post to see larger versions of the images below and video of what AIT images actually look like.

Advanced Imaging Technology: Storing, Exporting and Printing of Images

It's being reported that the Advanced Imaging Technology (also known as body scanners) being used by TSA has the ability to store, print and export images.

The truth is, the procurement specifications require these machines be capable of functioning in both a screening operation environment at the airport, and in a test mode environment. A test mode would be used at our testing facilities at the Transportation Security Integration Facility (TSIF) and the Transportation Security Lab (TSL). As you can imagine, the ability to store, export and print are crucial in a testing environment. TSA documents and manages approved configurations for all procured equipment, which are verified both in the factory and in the field prior to operational use.

All functionality to store, export or print images is disabled before these machines are delivered to airport checkpoints. There is no way for Transportation Security Officers in the airport environment to place the machines into test mode.

The Privacy Impact Statement (PIA), versions of which have been out since 2007, have each said the same thing: "While the equipment has the capability of collecting and storing an image, the image storage functions will be disabled by the manufacturer before the devices are placed in an airport and will not have the capability to be activated by operators."

AIT machines do have USB, hard disc and Ethernet capabilities, but these are for limited data transfer only - an officer's user ID, log-in and log-out time, and statistical data. Images cannot be transmitted or stored. Also, these machines are not networked, so they cannot be hacked.

TSA has been forthcoming with the traveling public about this technology, including the strong privacy protections we have in place. We've posted many times on Advanced Imaging Technology and you can read more on our blog and at TSA.gov.

Also, contrary to popular rumor, AIT portals cannot "beam you up."

On a slightly unrelated note, there are many different inaccurate images circulating out there. Below, you will see accurate examples of what our officers see while using advanced imaging technology. Anything else you see is inaccurate.

Response to: “Oops: Backscatter X-ray machines tear apart DNA"

This article has been receiving quite a bit of attention and it’s leading people to believe the Backscatter Advanced Imaging Technology (AIT) used by TSA emits terahertz radiation. Recent studies are showing that terahertz radiation may “unzip double-stranded DNA, creating bubbles in the double strand that could significantly interfere with processes such as gene expression and DNA replication.”

(I know… who knew that your DNA could be unzipped? Hey buddy, your barn door’s open!!!)

I forwarded the article around to a few subject matter experts here at TSA and was provided with some interesting information:

“TSA has not tested nor procured any terahertz AIT systems.”

That sentence should sum it up for most of our readers, but for those who like to get into the weeds, here is some more interesting information that was given to me from the fine folks at the Office of Security Technology (OST):

The Transportation Security Administration (TSA) has assessed multiple types of AIT systems including X-ray backscatter and millimeter wave. Both offer safe and effective whole body screening for weapons and explosives concealed on a person’s body. Backscatter X-ray technology uses X-rays that penetrate clothing, but not skin, to create an image. Millimeter wave technology uses sensors to collect millimeter wave energy to measure the difference in radiated energy relative to each object against a common background (the human body produces these signatures in typical screening applications) to construct a composite image.

Backscatter - Relies on a narrow, low intensity X-ray beam scanned over the body’s surface at high speed that is reflected back from the body and other objects placed or carried on the body, where it is converted into a computer image of the subject and displayed on a remote monitor. For comparison purposes, the X-ray dose received from the backscatter system is equivalent to the radiation received in two minutes of airplane flight at altitude (0.003* millirem by backscatter (2 scans) compared to .0552 millirem for two minutes of flight). Newer technologies require less scanning time, reducing individual X-ray exposure to .002 millirem for the entire process. The backscatter AIT meets and exceeds the American National Standards Institute (ANSI) standard for personnel security screening systems using X-rays.

Millimeter Wave - Uses non-ionizing radio frequency energy in the millimeter wave spectrum to generate an image based on the energy reflected from the body. The frequency range for millimeter wave technology exists in the range between 30-300 gigahertz. The three-dimensional image of the body is displayed on a remote monitor for analysis. The energy projected by the system is 10,000 times less than a cell phone transmission (.00000597 mW/cm2 for millimeter wave technology compared to 37.5 mW/cm2 for a cellphone).

Other Safety Information

“TSA security screening technologies are required to meet consensus standards, such as those issued by the American National Standards Institute (ANSI), as well as regulatory requirements such as those issued by the Food and Drug Administration (FDA). Our systems are independently tested as well by such laboratories as Johns Hopkins Applied Physics Laboratory (APL) and the National Institute for Standards and Technology (NIST) and FDA. We also apply an aggressive maintenance program to ensure that these systems continue to meet these performance standards. Additionally, TSA Occupational Safety Health and Environment (OSHE) is an active participant in our project integrated project teams. TSA OSHE assists in the development and validation of technology safety requirements. We also conduct safety evaluations as part of our laboratory, TSA Systems Integration Facility (TSIF), operational and site acceptance testing procedures.”

TSA tells its employees, namely Transportation Security Officers (TSOs), about the safety of advanced imaging technology machines, including the radiation exposure, during training on the equipment. In addition, TSA’s Office of Occupational Safety Health and Environment has individuals who work directly with TSOs to communicate safety information about operating the equipment. Information is available to TSOs through the OSHE Web site and employees can contact members of OSHE directly with questions.

TSA to Receive $355 Million for Airport Security Projects

(DHS) Secretary Janet Napolitano recently announced that TSA will receive $355 million for more than a dozen airport security projects funded by the American Recovery and Reinvestment Act (ARRA).

The $355 million is going to be used for a lot of really nifty improvements to aviation security including:

Inline Baggage Screening Systems: Inline baggage screening systems help keep transportation safe. $254 million will be spent on inline baggage handling systems at six airports—including Washington Dulles International Airport, Mineta San Jose International Airport, San Antonio International Airport, Portland (Maine) International Jetport, Port Columbus International Airport, and Hartsfield-Jackson Atlanta International Airport. Watch this video about inline baggage screening at ATL.

CCTV: $38 million will be spent to support new and enhanced closed circuit television (CCTV) systems at six airports, including Chicago Midway International Airport, Little Rock National Airport/Adams Field, Kansas City International Airport, Omaha Eppley Airfield, Washington Dulles International Airport, and Tampa International Airport.

Backscatter Advanced Imaging Units: Backscatter machines use advanced imaging technology that allow our officers to better detect a wide range of threats in a matter of seconds, including explosives. More than $25 million will fund the purchase and deployment of approximately 150 backscatter advanced imaging units to airports across the nation. This deployment follows a successful pilot phase, during which 46 imaging technology units were deployed at 23 airports and passengers opted to use imaging technology for primary screening 98 percent of the time. It is important to note that this technology is always optional to passengers.

Next Generation Explosives Trace Detection: If you’ve seen our officers swabbing passengers and luggage with white swabs, that is our Explosives Trace Detection (ETD) machines. ETDs can detect even the smallest traces of explosives and are a very important part of our layers of security. $15 million will be spent on Next Generation Explosives Trace Detection (ETD) units.

Next Generation Bottled Liquid Scanners: $22 million will be spent on Bottled Liquid Scanners (BLS), a technology that screens medically necessary liquids such as infant formula and liquid medications to ensure they do not contain a threat.

New Imaging Technology at Cleveland Hopkins Airport

With all of the comments on the TSA Blog about this technology, I just had to share the link to this article.

Check out this interesting read on Cleveland’s testing of new imaging technology:

Will Children be Screened by Whole Body Imagers?

This question keeps popping up on our blog as well as other forums around the internet. Will children be screened by Whole Body Imagers (WBI)?

Yes and no.

Anybody can opt out of WBI screening. Adults, children, Klingons, etc… If you opt out of WBI screening, you will receive a patdown search in lieu of the WBI screening.

Children are allowed to be screened by the WBI if they’re able to stand motionless with their arms outstretched and feet shoulder width apart for 5 seconds. (If your child is like my 4 year old, they can’t stand still for a single second unless they’re watching that yellow sponge guy who shares my name)

Things to remember:

- Children do not have to be screened by the WBI. (Anybody can opt out)
- Parents carrying infants or children will not be screened by the WBI.
- Parents accompanying children may opt out of WBI screening to prevent separation of family.
- WBI screening is still in the pilot phase and has not been deployed at all checkpoints.
- Did I mention you can opt out?

Which is it: Millimeter Wave or Backscatter?

As TSA continues to deploy new technology, some people continue to be confused about whole body imagers. Millimeter wave, backscatter, privacy filters… it all adds up to a confused traveling public.

Since one of our readers asked about the difference between millimeter wave and backscatter images in a previous post and we’ve also seen other blogs get the two confused, we thought we’d put the correct information and images out there to clear up any misinformation. Both millimeter wave and backscatter fall under the classification of whole body imaging, which gives security officers a virtual image of a passenger that highlights potentially dangerous items.

Here’s the lowdown on the two technologies:

How millimeter wave works:

Beams of radio frequency (RF) energy in the millimeter wave spectrum are projected over the body’s surface at high speed from two antennas simultaneously as they rotate around the body.


The RF energy reflected back from the body or other objects on the body is used to construct a three-dimensional image.

The three-dimensional image of the body, with facial features blurred for privacy, is displayed on a remote monitor for analysis. The image is not saved – once it’s off the screen it’s gone forever.

This is the millimeter wave image a security officer sees:

A millimeter wave machine looks like this:

Here’s how Millimeter Wave imaging works (WMV, 3.4 MB).

Here’s how Millimeter Wave technology detects threats (WMV, 3.4 MB).

How backscatter works:

A narrow, low intensity X-ray beam is scanned over the body's surface at high speed.
The technology relies on the X-ray radiation that is reflected back from the body and other objects placed or carried on the body, where it is converted into a computer image, embedded with a modesty filter and displayed on a remote monitor.

Passengers will walk up to the backscatter unit, assisted by a transportation security officer and remain still for several seconds while the technology creates an image of the body.
Images will be deleted immediately once viewed and will never be stored, transmitted or printed (the passenger imaging units have zero storage capability).

This is the backscatter image the security officer sees:




This is a backscatter machine.

And while we’re at it:

Because we see it time and time again, we wanted to clear up another bit of misinformation. This is a raw backscatter image with NO privacy algorithm. This is NOT what security officers see – this image was used to show what the capabilities of the technology are.
