South Carolina Brochure: Building Radon Out: What you need to know to keep you and your family safe

by Margaret Henderson

Based on data collected from testing, almost every county in South Carolina has test results that are elevated (above 4 pCi/L, the recommended USEPA action level). A county map shows number of tests, average results and highest levels. http://www.scdhec.gov/HomeAndEnvironment/Docs/Radon/Radon_Map_2015.pdf

Because the potential exists for new homes to have high levels and need remediation, the South Carolina Department of Health and Environmental Control Radon Program encourages radon resistant new construction. The department has published a brochure with the basic information about radon and about Building Radon Out: What you need to know to keep you and your family safe. http://www.scdhec.gov/Library/CR-010089.pdf

Clark Eldredge: 2017 Radon Hero

Clark Eldredge is recognized for his leadership and dedication to increasing radon awareness, radon testing and mitigation rates in the state of Florida for over 20 years. Clark has worked on various programs and initiatives during his tenure including a study on elevated radon levels on the 20th floor of a condominium. Clark has served as a member of the E-25 Committee on Radon and the Suggested States Regulations – Part R: Radon for many years. His invaluable guidance and incomparable expertise helped shape the Florida radon program and that has contributed extensively to radon activities at the state, regional and national level. He is an expert in risk communications by naturally engaging and motivating individuals on the importance of testing for the number one environmental carcinogen. As a science-driven leader, his unwavering commitment is demonstrated by his years of sustained exemplary leadership.

North Dakota Provides Explanations about Radon in a Variety of Ways

by Margaret Henderson

In North Dakota, the entire state is classified as Zone 1, High Potential, where radon levels are predicted to exceed 4 pi/L, the USEPA recommended action level. https://www.epa.gov/sites/production/files/2014-08/documents/north_dakota.pdf The map is not intended to suggest whether or not a home any county should be tested for radon; testing is the only way to determine what level of radon levels exists.

With the potential for the levels of radon to be so high statewide, the North Dakota Department of Health Radon Program provides educational outreach to offer information and resources to the public, with special emphasis on students and teachers.

Kansas Requires Testers, Mitigators and Laboratories to Report Data

by Margaret Henderson

The Kansas Department of Health and Environment (KDHE) collects radon data on testing and mitigation from contractors and laboratories. Kansas statute requires the information be shared and information is considered confidential. It may not be shared under “open records” provisions. The information is to be used by the department in studies.

The requirements are that “Any person who tests for radon in Kansas, analyzes radon testing devices used in Kansas, or performs radon mitigation in Kansas shall make a report of such testing, analysis, or mitigation to KDHE within 90 days. In order to make data submissions consistent and useful for studies, the department provides a downloadable form that includes fields for the topics that must be submitted. All submissions are to be made electronically.

South Dakota Offers the Basics on Radon

by Margaret Henderson

Much of the eastern portion of South Dakota is classified as Zone 1, High Potential, where predicted radon concentrations would be greater than 4 pCi/L, the USEPA recommended action level. The remainder of the state is classified as Zone 2, Moderate Potential, with levels predicted to be between 2 and 4 pCi/L. Radon test results, since the 1980s, have been collected and used to create a South Dakota “Radon Potential by County” map from comparisons with geological formations.

Due to the anticipated presence of radon in all of the state, the South Dakota Department of Environmental and Natural Resources encourages testing as the only way to know what radon concentrations are in any home. The Department provides technical radon assistance and provides a webpage about radon with general information.

Included in the basic information on radon provided are sections on:

  • How to test;
  • Mitigation; and
  • Resource links.

Maine Radon Program Offers Real Estate Guidance

by Margaret Henderson

The Division of Environmental Health in the Maine Department of Health and Human Services provides radon guidance regarding real estate. Maine statistics indicate that one of three homes in Maine has elevated radon. Based on the USEPA radon mapping, all Maine counties fall into Zone 1 and Zone 2. There are 28 counties in Zone 1, High Potential, where an average indoor radon screening level greater than 4 pCi/L, the USEPA recommended action level, is predicted. Nine counties fall into Zone 2, Moderate Potential, where the predicted average indoor radon screening level is between 2 and 4 pCi/L. No counties are categorized as Zone 3, Low Potential (less than 2 pCi/L predicted.

Save the Date: We hope to see you in Westminster, Colorado on April 19-20, 2018!

You are cordially invited to attend the EPA Region 8 Radon Stakeholders’ Meeting. This meeting is being held at no cost for all those who have a stake in protecting the public from unnecessary exposure to radon in their homes, schools and businesses.

EPA Region 8 and its partners, Colorado Dept. of Public Health and Environment, Montana Dept. of Environmental Quality, North Dakota Dept. of Health, South Dakota Dept. of Environment and Natural Resources, Utah Dept. of Environmental Quality and the Wyoming Dept. of Health seek to bring interested stakeholders together to discuss common issues and understand them from other perspectives, provide insight into the future, share, educate and network. We believe that meetings such as this will better provide all of us with ways to assist the public and reduce radon exposures.

“Protect Your Family From Radon: A Guide for New York State Residents"

by Margaret Henderson

The New York State Department of Health has published radon guidance in Protect Your Family From Radon: A Guide for New York State Residents. The publication, available in both English and Spanish, can be downloaded as a pdf brochure. https://www.health.ny.gov/publications/3168.pdf

The guide is designed for individuals and families and provides basic information about radon. The publication includes a list of the 41 counties in New York that are considered high risk. (High risk indicates that radon levels are anticipated to exceed 4 pCi/L, the USEPA recommended action level.) The department website also provides detailed maps and tables of radon test results in all counties in New York.

New Jersey Radon Outreach Includes Guidance on Radioactivity in Drinking Water

by Margaret Henderson

The New Jersey Department of Environmental Protection Radon Section has developed outreach strategies to educate the public about radon risks. Radon information includes data on indoor radon test results collected over almost 30 years and guidance on radioactivity in water from private drinking water wells. Public interest in radon and the role of drinking water in increasing indoor radon have prompted detailed information on the prior testing and guidance on testing drinking water.

The Radon Section provides a Radon Potential Map (2015) that includes data on more than one million radon indoor tests, performed between 1985 through 2014. Levels exceeding 4 pCi/L, the recommended USEPA action level, have been found in every area of New Jersey, regardless of radon potential designed by the map.
