Indiana Mapping Promotes Interest in Testing for Radon

by Margaret Henderson

The Indiana State Department of Health, Indoor Air Quality Program, provides information about Indiana radon potentials and levels and radon prevention and mitigation.

All counties in Indiana are categorized as either Zone 1 or Zone 2 counties, per the USEPA classification.

  • Zone 1 includes counties with predicted average indoor radon screening levels greater than 4 pCi/L.
  • Zone 2 includes counties with predicted average indoor radon screening levels from 2 to 4 pCi/L.

With such high potential for excessive indoor radon, the Program advises the public that the only way to know if you have a radon problem is to test your home. To encourage testing and mitigation and inform the public about radon potentials and findings in their areas, the Program has provided test radon data through a number of maps in order to report findings in understandable, visual ways.

Missouri Maps and Reports Radon Testing in Public Schools

by Margaret Henderson

The Missouri Department of Health and Senior Services provides radon information for the public, including data on radon testing in public schools. Most of the state’s counties are in Zone 2, the USEPA classification, where predicted average indoor radon screening levels would be from 2 to 4 pCi/L. Eleven counties are in Zone 1, where predicted average indoor radon screening levels greater than 4 pCi/L, the recommended USEPA action level.

Interactive mapping of radon testing in public schools allows filtering by county and school name in order to zoom to results or statewide data can be viewed of all counties and districts. Selections include public schools and districts tested. Map background may be chosen. https://ogi.oa.mo.gov/DHSS/EPHT_radonSchool/index.html

Kansas Data on Testing During Real Estate Transactions

by Margaret Henderson

The Kansas Department of Environmental Health and the Kansas Radon Program have analyzed radon data collected over two decades, frequently finding data reveals elevated radon levels. In Kansas, most of the counties are classified as Zone 1, per the USEPA classification. Zone 1 includes counties with predicted average indoor radon screening levels greater than 4 pCi/L.

Data through 2014 is presented in a county map of the state with a total number of measurements equal to 73,959. Of those, 31,539 exceeded the USEPA recommended action level of 4 pCi/L. Measurements of 20 pCi/L or greater were reported in 1,957 results. The maximum reported radon level was 1,121.6 pCi/L and the average radon level was 5.1 pCi/L.

Working With Real Estate Professionals in Illinois

There is no law requiring that a radon test be performed on residential properties. However, the Illinois Residential Real Property Disclosure Act requires sellers to disclose known radon levels of 4.0 picocuries per liter of air (pCi/L) or more. The United States Environmental Protection Agency (USEPA) has designated 4.0 pCi/L as the action level, the level at which mitigation is recommended to reduce indoor radon levels.

The Illinois Real Property Disclosure Act of 1993 included radon disclosure on a checklist that states “I am aware of unsafe concentrations of radon on the premises.”

Save the Date of January 11, 2018, for the Next MDH and NS-AARST Stakeholder Meeting

The Minnesota Department of Health (MDH) in partnership with the North Star Chapter of the American Association of Radon Scientists and Technologists (NS-AARST) ask you to Save the Date of January 11, 2018 for the next MDH and NS-AARST Stakeholder meeting. The meeting will begin promptly at 9:00 AM.

Who: Minnesota Radon Stakeholders including measurement and mitigation professionals, health officials and partners

What: First MDH Stakeholder Meeting of 2018

Where: Blaine Fire Department - 11920 Ulysses St NE, Blaine, MN 55434

When: Thursday January 11, 2018 at 9:00 AM

This will be very similar to the past Radon Stakeholder meetings and NRPP Continuing Education Credits will be made available to those who need them. We will be applying for 6 hours of Category 1 type hours. Lunch will be provided, but a registration fee may be charged by NS-AARST to cover the cost of lunch and snacks.

New Mexico’s Indoor Radon Outreach Program

by Margaret Henderson

New Mexico Environment Department Radiation Control Bureau operates the “Indoor Radon Outreach Program” in order to provide public education about the health risk of radon gas, and information on methods for mitigating excess indoor radon. The Program is funded by the U.S. Environmental Protection Agency (EPA).

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.
