Breathing Easy: What Home Buyers and Sellers Should Know About Radon
![](https://webarchive.library.unt.edu/web/20081107161544im_/http://www.epa.gov/radon/images/video_capture.jpg)
The video satisfies a long-standing need for a short visual educational tool on how to best include radon in residential real estate transactions. With a bit of light humor, the video covers the basics, including radon science, the lung cancer risk, home inspection, building a new home radon-resistant, testing and fixing a home, disclosure, state radon offices, hotline and web resources, and key radon numbers, e.g., EPA's action level and the U.S. indoor and outdoor averages.
The primary audiences are home buyers and sellers, and real estate sales agents and brokers. Home inspectors, mortgage lenders, other real estate practitioners, and radon services providers will also find the video helpful.

Contractor Report: Exploratory Study of Basement Moisture During Operation of ASD Radon Control Systems (March 2008)
EPA’s Indoor Environments Division commissioned an Exploratory Study of Basement Moisture During Operation of ASD Radon Control Systems, under a cooperative agreement with Auburn University, Auburn, Alabama. The principal investigator was Brad Turk of Environmental Building Sciences, Inc., Las Vegas, New Mexico. The purpose of the study was to better understand the potential moisture reduction benefits from the operation of residential radon control systems. The report contains information of interest to a wide variety of audiences. Therefore, EPA is making this contractor’s report publicly available. Because it is a contractor’s report, its findings, conclusions and recommendations are those of its authors, not necessarily those of EPA. The Agency believes that this information may be useful to industry associations, standard-setting organizations, government agencies and consumers.
The principal investigators are currently conducting an extended analysis of the existing information and data. That analysis is expected to be completed by June 1, 2008. At that time, the Agency will develop a public position on the additional analysis and the report’s findings and recommendations.

EPA’s Recommended Residential Radon Mitigation Standard of Practice
EPA recommends the Standard Practice for Radon Mitigation Systems in Existing Low-Rise Residential Buildings* for residential radon mitigation. The Agency
initially recognized this standard in 2003 as the most appropriate guide to reducing radon in homes as far as practicable below the national action level
of 4 pCi/L in indoor air. A single free copy of the E-2121 standard is available from the Agency’s National Service Center for Environmental Publications.
Copies of the standard may be purchased from ASTMI
*E-2121-03 (February 10, 2003), American Society for Testing and Materials International (ASTMI); an American National Standards Institute (ANSI) approved consensus standard. Note: As of May 2006, EPA's Radon Mitigation Standards (EPA 402-R-93-078, Revised April 1994) is no longer recommended or available. To control for radon in new residential construction, EPA recommends the use of ASTM’s Standard Practice for Radon Control Options for the Design and Construction of New Low-Rise Residential Buildings*. A single free printed copy of ASTM E 1465-07a is available from EPA upon request. Use EPA’s document number (402-K-07-010) when ordering from the National Service Center for Environmental Publications. *ASTM E1465-07a; July 15, 2007. EPA reprints E1465-07a by permission with ASTM.
