Arizona Guidance on Radon Mitigation

by Margaret Henderson

The Arizona Radiation Regulatory Agency has extensive information about Radon Mitigation at https://arra.az.gov/radon/about-radon/mitigation

While the radon incidence in Arizona is considered similar to the average nationwide, this means about 1 out of 15 homes may contain radon concentrations in excess of 4.0 pCi/L, the USEPA recommended action level. Uranium mining was conducted in Arizona in the 1950s and 1960s, so the presence of uranium in the soil is well known and may result in radon concerns for homeowners. The amount of uranium and radium in the soils may vary statewide and the only way to know the indoor radon level is to test, the Agency encourages.

To offer guidance on what to do if elevated levels are found, the Agency has assembled information on its website to address:

All Homes Can be Fixed
How do I treat radon?
Crawl Spaces
Slab-on-Grade Homes
Drainage Systems
Under Slab Ductwork
Air Filtration Systems

Educating North Carolina Brokers About Radon

The mission of the North Carolina Real Estate Commission is to protect the public interest in real estate brokerage transactions, and radon is an issue of public interest in the state. Homes in all 100 counties in North Carolina have had test results revealing high levels of radon.

Michigan’s Indoor Radon Program

Contributed by Aaron Berndt

The Michigan Indoor Radon Program’s primary focus is on outreach and testing. The program has two major partners in the Michigan Association of Broadcasters (MAB) and local health departments. MAB broadcasts over 18,000 public service announcements statewide for the Radon Program around Radon Action Month in January. The Radon Program has distributed over 18,000 test kits already this year along with various other outreach materials to the local health departments. This is instrumental in raising awareness locally in their communities and to increase radon testing in homes.

Program Staff participates in many outreach events statewide every year including but not limited to:
• various state and national conferences;
• home shows;
• local health department outreach events;
• annual meetings; and
• continuing education training sessions for realtors, appraisers, and home inspectors.

In Utah, the buyers due diligence checklist includes radon. Reference the Utah Association of Realtors at https://pscdocs.utah.gov/electric/16docs/16035T13/290524ExBBuyerDueDiligChecklist11-29-2016.pdf

The Minnesota Radon Awareness Act (https://www.revisor.mn.gov/statutes/?id=144.496) disclosure requirements include a radon warning statement with the language:

Radon Warning Statement:
The Minnesota Department of Health strongly recommends that ALL homebuyers have an indoor radon test performed prior to purchase or taking occupancy, and recommends having the radon levels mitigated if elevated radon concentrations are found. Elevated radon concentrations can easily be reduced by a qualified, certified, or licensed, if applicable, radon mitigator.

Washington Tracking Network Includes Geology Layer With Radon Data Mapping

by Margaret Henderson

The Washington State Department of Health website provides the Washington Tracking Network (WTN), A Source for Environmental Public Health Data, that includes radon data and allows selection of geology as a map layer. Test results from 1989-2016 are provided and can be viewed as “number of houses tested” or “test results.” An additional map layer may be added to show geology statewide, or by county or census tract. The geology layer is another means to encourage testing each residence, even though test results in the area may not have elevated radon levels.

The geology layer indicates the surface geology and the potential for radon exposures to be high, medium or low. The levels, which categorized 57,000 identifiable rock and soil types, are defined as:

  • High - geology contains uranium, or has rock types known to contain uranium.

In cooperation with and funding from the Center for Disease Control and Prevention, the Utah Department of Health (UDOH) had built the data networks and local tracking program needed to provide radon data to the public.

The available radon data portals are a publicly-accessible repository of radon data:
• Utah: http://epht.health.utah.gov

CR3 News November Issue celebrates National Lung Cancer Awareness and Veterans Day

Hope you will open, read, and share our electronic magazine, CR3 NEWS, this
month which highlights many veterans saving lives with radon reduction and our
radon-induced lung cancer survivors advocating for lung cancer awareness and
prevention on capitol hill and at the National Press Club! We appreciate the
talents and determination of our publisher, Jackie Nixon, lung cancer survivor
and publisher of our magazine. https://view.joomag.com/2017-citizens-for-radioactive-radon-reduction-news-november-issue/0067864001507578599?short

Mapping Illustrates Washington DC Radon Data and Encourages Testing

by Margaret Henderson

The Washington DC Department of Energy and Environment provides outreach and education about radon in a variety of ways, including illustrating the radon test data through mapping.

“Home Radon Test Kit Results in DC and Maryland” (2010-2015) illustrates radon test findings.
Additional mapping of 2010-1012 data is show in “Spatial Distribution of Indoor Radon.” The maps show that majority of results appear to be less than 4pCi/L, the EPA recommended action level. However, higher levels are found in various areas, indicating a need to test for radon to be sure about the levels in each residence.

Tennessee Interactive Radon Map Provides Radon Data and Geological Detail

by Margaret Henderson

Tennessee Department of Environment and Conservation operates the statewide radon program for indoor air as part of the Office of Sustainable Practices. Outreach activities include providing services and technical information, free test kits, and educational materials.

About 16% of homes in Tennessee are expected to have radon present in excess of 4 pCi/L, the USEPA recommended action level. Some areas of the state have the potential for 33-75% of the homes to have excess radon levels.

An interactive Tennessee Radon Map presents data from January 1, 2009 to October 31, 2014 from Short-Term Indoor Air Radon Test Results.
