Kansas Adopts Quality Assurance Plan for Conducting Radon Measurements

by Margaret Henderson

Kansas Department of Health and Environment (KDHE) Quality Assurance Plan for Conducting Radon Measurements, dated January 30, 2018, sets forth requirements for technicians employed by the Kansas Department of Health and Environment who perform radon measurements. The plan is to be reviewed and revised annually and its goal is to assure radon measurements conducted by the department are accurate, consistent and reproducible.

The KDHE Radon Program provides technical assistance to the residents of Kansas by providing measurement and mitigation technical information. The Program also is involved in oversight and certification of measurement and mitigation professionals and radon laboratories. Services may be provided as funds are available and may be performed in regulatory actions as needed.

The plan includes instructions on:
• Documents and Records
• Measurement Generation
• Sampling Methods
• Analytical Methods
• Instrument Calibration

Low Income Mitigation Assistance in Minnesota - MAY 30 DEADLINE

by Margaret Henderson

Due to Minnesota’s geology and building types and climate of long winter weather, two in five homes in Minnesota have high radon levels, in excess of the US EPA 4pCi/L recommended action level. Approximately 80% of Minnesota counties are expected to have high radon potentials.

For persons for whom mitigation is unaffordable, the Radon Program recognizes the need to provide special information that may help in making mitigation attainable.
The Minnesota Department of Health provides information about financial assistance to low income persons for mitigating radon. Depending on availability of funds, the Radon Program notes these possible sources:

  • Minnesota Housing Finance Agency (MHFA), offering low-interest fixed rate loans;
  • US Department of Housing and Urban Development - HUD "203k" Program, offering some loan programs;
  • Rural Repair and Rehabilitation Loans and Grants, offering loans and grants.

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
