Radiofrequency and Microwave Radiation
Radiofrequency (RF) and microwave (MW) radiation are electromagnetic radiation in the frequency ranges 3 kilohertz (kHz) - 300 Megahertz (MHz), and 300 MHz - 300 gigahertz (GHz), respectively. Research continues on possible biological effects of exposure to RF/MW radiation from radios, cellular phones,
the processing and cooking of foods, heat sealers, vinyl welders, high frequency welders, induction heaters, flow solder machines, communications transmitters, radar transmitters, ion implant equipment, microwave drying equipment, sputtering equipment and glue curing.
There are no specific standards for radiofrequency and microwave radiation issues.
Standards
This section highlights OSHA standards, standard interpretations (official interpretation of the standards), other federal, national consensus, and foreign national standards relevant to radiofrequency and microwave radiation.
OSHA
Note: Twenty-five states, Puerto Rico and the Virgin Islands have OSHA-approved State Plans and have adopted their own standards and enforcement policies. For the most part, these States adopt standards that are identical to Federal OSHA. However, some States have adopted different standards applicable to this topic or may have different enforcement policies.

Health Effects
Electric and magnetic fields are complex physical agents
whose potential health effects are the subject of much research. Particularly
controversial are the biophysical mechanisms by which these RF
fields may affect biological systems. General health effects reviews explore
possible carcinogenic, reproductive and neurological effects. Health effects by exposure source are noted in radar traffic devices, wireless communications with cellular phones, radio transmission, and magnetic resonance imaging (MRI).

The incidents occurred in 1995 and 1996.
Magnetic Resonance Imaging (MRI)
Hazard Locations and Solutions
In recent years there has been considerable discussion and concern about the possible hazards of RF/MW radiation. Extensive research on this topic is underway in many countries. Natural low-frequency EM fields come from two main sources: the sun, and thunderstorm activity, but man-made fields at much higher frequencies have altered this natural EMF. At sufficiently high power densities, RF/MW energy can cause thermal effects that can cause blindness, and sterility. Non-thermal effects, such as alteration of the human body's circadian rhythms, immune system and the nature of the electrical and chemical signals communicated through the cell membrane have been demonstrated. However, none of the research has conclusively proven that low-level RF/MW radiation causes adverse health effects.

Interference with Medical Devices
- Human Exposure to Radio Frequency and Microwave Radiation from Portable and Mobile Telephones and Other Wireless Communication Devices. Institute of Electrical and Electronics Engineers (IEEE) Committee on Man and Radiation (COMAR), (2000, September). Reports that sufficiently high levels of RF energy can interfere with other electronic equipment. This problem is more likely to occur with pulsed energy, which characterizes digital cellular telephones. Studies have shown that handheld cellular phones can affect the operation of heart pacemakers or defibrillators if the phone is placed directly over the device, and there have been reports of interference between cell phones and hearing aids. Individuals with pacemakers, implantable defibrillators, or other body-mounted medical electronic devices, should consult with their physician and/or the phone manufacturer to determine what precautions, if any, should be taken. Some manufacturers recommend that cell phones be used on the other side of the body from the implanted pacemaker.
- Electromagnetic Compatibility - EMC. Food and Drug Administration (FDA), Center for Devices and Radiological Health (CDRH).
- Update on Cellular phone Interference with Cardiac Pacemakers. (1995, November 1). Reports interference with the pacemaker's normal delivery of pulses can occur when some cellular phones are placed very close to implanted cardiac pacemakers, The type of interference under study is called "electromagnetic interference", or "Emi". The CDRH concludes that interference issues are limited to TDMA-type digital technologies, and further, that a distance separation of ~6 inches (~15 cm) is sufficient to mitigate EMI.

- "Use Of "Protective Devices" For Cellular Telephones Technical Information Statement." Institute of Electrical and Electronics Engineers (IEEE) Engineering in Medicine and Biology Magazine 21.3(2002):105-6. If a mobile-phone user wants to reduce his or her exposure to RF energy, for whatever reason, he or she can:
- Limit the duration of calls
- Use a digital handset instead of an older analog model. In most, but not all cases, digital handsets operate at lower power levels than analog models. (The actual power level, however, depends on local conditions and can vary greatly.)
- Use "hands-free kits", which move the handset away from the body.
- Human Exposure to Radio Frequency and Microwave Radiation from Portable and Mobile Telephones and Other Wireless Communication Devices. Institute of Electrical and Electronics Engineers (IEEE) Committee on Man and Radiation (COMAR), (2000, September). Indicates that local SARs produced by hand-held, transportable, and mobile transceivers and cellular telephones normally do not exceed FCC and other safety limits. Present scientific evidence, as reviewed by standards setting organizations and other expert groups, does not demonstrate health or safety risks from cellular and other communications transceivers. A potential exists for interference between hand-held units and some medical devices that may be located in close proximity to them (within a few centimeters).
- Physical Agents Data Sheets (PADs) - Radiofrequency/Microwave Radiation. Alaska Department of Labor and Development. Requires employers who have people working around devices which produce radiofrequency/microwave radiation ensure that those devices are properly shielded to prevent leakage of radiation. The State of Alaska in its Alaska Occupational Safety and Health Standards has specified for incident electromagnetic energy frequencies from 10 MHz to 100 GHz, a Permissible Exposure Limit (PEL) of 10 mW/cm as averaged over any possible six-minute period.
Heating and Sealing Devices
- Radiofrequency (RF) Sealers and Heaters. OSHA, the US Department of Health and Human Services (DHHS), and the National Institute for Occupational Safety and Health (NIOSH) Joint NIOSH/OSHA Current Intelligence Bulletin No. 33, (1979, December 4). Recommends that precautionary measures be instituted to minimize the risk to workers from unwarranted exposure to RF energy. The following controls are recommended:
- Properly design and install shielding material.
- Maximize the distance between the worker and the source of RF energy emission should be maximized. Examples of means to accomplish this include the use of automatic feeding devices, rotating tables, and remote materials handling.
- Tune the equipment electronically to minimize the stray power emitted.
- Whenever possible, equipment switch off equipment when it is not being used. Maintenance and adjustment of the equipment should be performed only while the equipment is not in operation.
- After the performance of maintenance or repair, all machine parts, including cabinetry, should be reinstalled so that the equipment is intact and its configuration is unchanged.
- Post warnings and information.
- Develop a medical surveillance program tailored to the expected degree of employee use of RF equipment and potential for exposure to RF energy.
- Take exposure measurements at regular intervals.
- Physical Agents Data Sheets (PADs) - Radiofrequency/Microwave Radiation - Safety and Health Precautions. Alaska Department of Labor and Workforce Development. Reports radiofrequency sealers and heaters have been among the major sources of employee exposure to radiofrequency/microwave radiation.
- When these machines are used, employees should use mechanical or electrical devices that allow them to stay as far away form the source of radiation as possible.
- Whenever possible, these sealers should be turned off when not being used. Maintenance and adjustment of this type of equipment should be performed only by trained technicians and only when the machines are turned off.
- Warnings should be posted to keep everyone away from the source of radiation except for those workers who are absolutely essential to performing the job.
Microwave Ovens
- Microwave Ovens and their Hazards. Canadian Centre for Occupational Health and Safety (CCOHS). Identifies old or faulty door seals as the most common causes of microwave radiation leakage. Mechanical abuse, a build-up of dirt, or simple wear and tear of continued use can cause door seals to be less effective. Theoretically, there will be small amounts of leakage through the viewing glass but measurements have shown this to be insignificant. Safety tips for installation and maintenance of microwave ovens include:
- Take special care to ensure that no damage occurs to the part of the oven making contact with the door or door seals.
- Ensure that the microwave is unplugged or disconnected from electrical power before reaching into any accessible openings or attempting any repairs.
- Ensure that the adjustment of applied voltages, replacement of the microwave power generating component, dismantling of the oven components, and refitting of waveguides are undertaken only by persons who have been specially trained for such tasks. The services of a qualified repairman should be sought when any malfunction is suspected.
- Do not by pass the door interlocks.
- Do not test a microwave power generating component without an appropriate load connected to its output. The power generated must never be allowed to radiate freely into occupied areas.
- Microwave Oven. Food and Drug Administration (FDA), Center for Devices and Radiological Health (CDRH). Contains FAQs about microwave ovens, checking ovens for leakage, tips on safe microwave oven operation, and the erupted Hot Water Phenomena in Microwave Ovens.

-
Occupational Exposure of Police
Officers to Microwave Radiation from Traffic Radar Devices.
National Institute for Occupational Safety and Health (NIOSH),
National Technical Information Service (NTIS) Publication No. PB95-261350, (1995,
June). Recommends police officers take some simple steps which
will sharply reduce their exposure to the low-level microwave radiation which
these devices emit.
- Always point the device away from the police officer's body, or his/her partner's body,
while it is turned on.
- Mount fixed radar antennas so that the beam is not pointed at any
occupant of the patrol car.
- Whenever possible, turn off a hand-held unit when it is not in use. If
the police officer's unit has a "standby" mode, always use it when not measuring the speed
of a vehicle. Never rest the unit against the officer's body when it is turned on.
- When it is on, try to avoid pointing the device toward metal surfaces
inside the police officer's car, such as the floor or a door, to avoid microwave reflection.
Evaluating RF and Microwave Exposure
RF energy includes frequencies ranging from about
3000 cycles per second (3 kHz) to 300 billion cycles per second (300 GHz).
Microwaves are a subset of radio waves and includes frequencies ranging from around
300 million cycles per second (300 MHz) to 3
GHz. RF exposures are directly linked to
absorption and distribution of RF energy in the body, and the absorption and
distribution are strongly dependent on body size and orientation and on
frequency and polarization of the incident radiation. A common measure of exposure is the Specific Absorption Rate
(SAR), the rate of energy absorption in tissue, measured in watts per kilogram
of tissue.

Stations
Amateur Radio
-
Radiofrequency Safety FAQs. Federal Communications Commission (FCC)
- American Radio Relay League (ARRL)
- The FCC's New RF-Exposure Regulations. Describes the FCC regulations which identify Maximum Permissible Exposure (MPE) derived from the Specific Absorption Rate
(SAR) at which tissue absorbs RF energy, expressed in watts per kilogram (W/kg). From a safe SAR, the Standards and regulations set MPEs that vary with frequency. Human-body resonances fall in the frequency range from 30 to 300 MHz and are the most strictly controlled. The regulations define two primary RF-exposure environments "controlled/occupational" and "uncontrolled/general public." In a "controlled" RF environment people know that RF is present and can
take steps to control their exposure. This applies to areas where you control access. The limits for controlled environments are evaluated differently (less stringent) than those for uncontrolled environments.
- FCC RF-Exposure Regulations -- the Station Evaluation. Provides the power-density and field-strength formulas and tables which give the compliance distance in the main beam of the antenna, at any angle. The tables based on antenna modeling have calculated the horizontal compliance distances at ground level, and at first and second story exposure levels.
- Measurements of Electromagnetic Fields at Amateur Radio Stations. OET Report ASD-9601, (1996, January).
Also available as a 145 KB PDF, 70 pages. Describes a joint measurement study of environmental radiofrequency (RF) fields in the vicinity of nine amateur radio stations that was conducted by the FCC and the U.S. Environmental Protection Agency (EPA) in southern California. Measurements of electric and magnetic field strength were made in areas near amateur antennas and equipment in order to determine typical and "worst case" exposure levels.
