Kansas Provides Resources for Radon Contractors

by Margaret Henderson

The Kansas Department of Heath and Environment (KDHE) provides information and resources for contractors who, by law, must have a current certificate to perform radon testing or mitigation work and must be aware of and/or abide by various specifications. Topics of these specifications include:
• Certification
• Real Estate
• Standards and Protocols
• Building Codes
• Training and Examinations

The Radon Program provides links to the Kansas laws that require certification of persons. Application forms and fee schedules are also provided. All are available on the website http://www.kdheks.gov/radiation/radon_laws.htm

Real Estate
Kansas law also addresses requirements in real estate transactions. Information about radon and a recommendation to test for radon must be provided to all home buyers on their residential real estate contract.


Arizona Provides Detailed Radon Information and Has Developed Long-Term Program Goals

by Margaret Henderson

Arizona Department of Health Services, Bureau of Radiation Control, Radon Program, through the State Indoor Radon Grant Program, provides a variety of radon activities. The Program continues to assess the radon hazards in Arizona, encourages testing and mitigation, educates the public about radon and performs measurements in public schools and buildings.

In Arizona, approximately one in fifteen homes has elevated radon levels (in excess of the USEPA recommended action level of 4 pCi/L). The geology of Arizona, where uranium mining occurred from the 1950s, contributes to the presence of radon. The Program encourages testing, regardless of proximity to uranium mining locations and emphasizes that the only way to know the radon level in a home is to test.

CRCPD Cooperates in First Radon Webinar Held by IAEA

by Margaret Henderson

April 5, 2018, the International Atomic Energy Agency (IAEA) held its first Radon Webinar, “Targeting Radon: Sharing Practices and Experiences.” The focus of this webinar was improving radon messaging about buying and selling a home.

Tennessee Provides Data, Advice and Free Test Kits

by Margaret Henderson

Tennessee Department of Environment and Conservation Radon Program, part of the Office of Policy and Sustainable Practices, provides information, assistance and technical information to the public in order to encourage testing and mitigation of radon in excess of the USEPA recommended standard of 4 pCi/L.

Approximately 16% of the homes in Tennessee are expected to have high radon and in some areas, the percentage could be as high as 33 to 75%. To give the public some idea of radon levels in the areas near their homes, the Program provides an Radon Interactive Map.
See https://www.tn.gov/health/cedep/environmental/epht/interactive-radon-map.html

This map, based on data from 2009-2014, gives test results and other information by county. For instance, for Marshall County, the following information is provided by clicking on the map:

Oklahoma Department of Environmental Quality Brochure on Radon

by Margaret Henderson

The Oklahoma Department of Environmental Quality Radon Program provides education and public outreach to answer questions about radon and encourage testing and mitigation.

Radon in Oklahoma is a brochure published by the Radon Program to provide basic information on topics surrounding radon. http://www.deq.state.ok.us/radon/radon%20in%20oklahoma%20brochure.pdf

The brochure suggests using radon resistant new construction techniques when building a new home, and provides some basic discussion of:
• What is Radon
• Radon Risks
• How Radon Enters the Home

Radon mitigation advice includes possibilities such as sealing cracks in floors and walls or installing mitigation systems when needed. Cost estimates are given for mitigation with average costs being around $1200 and anticipated ranges of $800 to $2500.

Maryland Mapping Tools Provide Public Information

by Margaret Henderson

The Maryland Department of Health has presented new mapping in order to promote knowledge about radon in Maryland and its health effects and encourage testing for radon. Data provided for testing between January 2005 and April 2016 was supplied by laboratories including those of Air Chek, Inc., Alpha Energy Labs, Landauer Radon, RAdata Inc., and Radon Testing Corp of America, Inc.

The interactive map offers a variety of base maps and provides information by county. The county-level statistics include the number of measurements reported and the average radon concentrations. Concentrations reported are divided into four categories with averages in pCi/L of:
• 4.01 – 60.58
• 2.01 – 4.0
• .01 – 2.0
• 0
The number of samples range from:
• 150- 1293
• 50 – 149
• 10 – 49
• 0

The clickable map presents findings that include the following and allows the user to zoom in to the area:
• Average
• Count number
• Maximum radon concentration

Interactive California Radon Potential Map

by Margaret Henderson

The California Geological Survey has released an interactive map that provides information on radon potential in areas of California where the Survey has completed radon potential maps. See the map at http://maps.conservation.ca.gov/cgs/radon/
The map was produced in cooperation with the California Department of Public Health Radon Program. The map is intended to guide residents in understanding where radon may be found in excess of the USEPA recommended action level of 4 pCi/L; however, testing is recommended in all areas. Geographic Information System (GIS) data for each study area can now be downloaded through the interactive map.

The user may search for data by entering the location name, or by clicking on the map. In those areas where the radon potential mapping has been completed, results are provided. A pop-up block gives the information such as:
Potential: High

Oregon Updates Radon Risk Map

by Margaret Henderson

The Oregon Health Authority Radon Awareness Program has updated its Radon Risk Map, effective January 2018. The Program uses the interactive map to inform the public of potential hazards of radon. Encouraging testing, mitigation and radon resistance new construction are other missions of the Program. According to the Authority, there are approximately 276 radon-related lung cancer deaths each year in Oregon.

Maryland’s Activities for Radon Awareness Week

by Margaret Henderson

Governor Hogan of Maryland began Radon Action Month with a proclamation, naming Radon Gas Awareness Week, January 21 – 27, 2018. The Maryland Department of Health, Housing and Community Development, together with local health departments joined to educate Maryland residents about the hazards of radon.

The Department of Health and Department of the Environment produced a brochure on Maryland Radon Facts to provide the basics to the public.

Tools for Local Health Departments were made available through the Department of Health website, which included:

Pennsylvania Messaging About Radon Carried by Various Outlets

by Margaret Henderson

In Pennsylvania, 40% of the homes tested have elevated radon levels, in excess of the 4 pCi/L recommended action level of the USEPA. The Pennsylvania Department of Environmental Protection (DEP) provides outreach and assistance to the public in an effort to encourage testing and mitigation.

For National Radon Action Month, several outlets presented the Department’s messaging on radon. In a video interview on abc27.com, Bob Lewis of the Radon Division, was interviewed and featured on the website of the station. Mr. Lewis discussed why elevated radon levels may occur; about how to test and what results mean; and when and how to mitigate excessive radon concentrations in the home.
