Nevada Publication Provides Information and Provides an “Ask the Professor” Feature

by Margaret Henderson

Nevada Today, an on-line publication of the University of Nevada Reno, featured an article by Susan Howe, Director of the University of Nevada Cooperative Extension's Radon Education Program in which she explains why it's important to check for radon in your home. http://www.unr.edu/nevada-today/news/2017/atp-radon

The program’s activities are a grant-funded outreach program, funded by the Nevada Division of Public and Behavioral Health. The “Ask the Professor” feature of the article provides a contact form in which the reader may ask a professor a question about radon.

In the article, Ms. Howe encourages testing, radon resistant new construction, and mitigation when necessary. The article also provides links to the Radon Poster winner for 2017 and to a series of outreach meetings conducted during 2017.

Rhode Island Radon Control Program Provides Wide Array of Guidance

by Margaret Henderson

Rhode Island Department of Health, Radon Control Program, provides guidance to the public on a variety of radon topics. In Rhode Island, the average radon level is almost three times the national average. One in four homes tested has exceeded the USEPA recommended action level of 4 pCi/l. More than 50% tested homes in Exeter and Richmond exceeded this level (2011 database). Therefore, making public information widely available is an important mission of the department.

To provide information to the public, the department uses its website to provide a wide variety of information for businesses and residents.

Some guidance includes:

• Radon in drinking water wells http://web.uri.edu/safewater/files/TipSheetC13-Radon.pdf

Announcement and Invitation to the 27th National Radon Training Conference

Wisconsin Data on Radon Presented in On-line Mapping Tool

by Margaret Henderson

The Wisconsin Department of Health Services provides radon information at https://www.dhs.wisconsin.gov/radon/index.htm. Data on radon tests are presented on-line so that residents can find out where radon test results have been the highest. An interactive map, “Wisconsin Indoor Radon Levels,” features test results give in average radon levels and the percentage of test results greater than or equal to 4 pCi/L, the recommended USEPA action level. http://wi-dhs.maps.arcgis.com/apps/OnePane/basicviewer/index.html?appid=a0f619747b5e4e72bce960619e6663e8

Alabama Provides Testing Instruction for Karst and Non-karst Areas

by Margaret Henderson

Radon in Alabama homes can vary from home to home and throughout the state, which includes all three radon zones (EPA designation) for high, moderate and low concentrations of radon. Fifteen counties in Alabama have the highest potential for elevated radon (exceeding 4pCi/L, the EPA recommended action level). Additionally, the type of geologic formations in Alabama introduce an additional element of uncertainty in testing that is important to note.

Nevada “My Hazards Map” Includes Radon

by Margaret Henderson

A collaboration between the Nevada Radon Education Program and the Nevada Bureau of Mines and Geology has produced a “My Hazards Map” which includes radon, along with other categories of hazards (fires, floods, earthquakes) with choices of base layer (satellite imagery, streets, etc.).

The interactive map with multiple hazard layers can been seen at
https://gisweb.unr.edu/MyHAZARDS/ The American Geosciences Institute Critical Issues termed it the “map of the day” on Twitter on June 6.

Indoor Radon Risk Levels in Oregon

by Margaret Henderson

The Oregon Public Health Division, Radon Awareness Program, recommends testing all Oregon residences regardless of the risk level assigned to the home's geographic location. In Oregon an estimated 276 radon-related deaths occur each year, according to the department.

To help residents understand the level of radon risk associated with living in various areas of the state, the department presents data and assigns risk scores. The data includes long-term radon tests (more than 90 days) and short-term radon tests (2-90 days) that have been conducted primarily by homeowners among a group of homes, even those next door to each other.

Information is available in a risk level map for radon using arcgis (geographic information systems presentation).

South Carolina Presents Radon Data by County in State Map

by Margaret Henderson

The South Carolina Department of Health and Environmental Control (SCDHEC) used results from test kits analyzed by its laborary, from kits provided to residents who tested their homes. Test kit data through December 31, 2015, is presented on-line in a county map, giving average in-home radon concentrations.

For each county, the average result, highest level and number of tests are given. The highest level of 126.6 pCi/L was in Greenville County [Number of Test: 4654; Average Result: 4.2 pCi/L].

The map advises, “Just because the average for your county may not be as high as others, it is possible that you have elevated radon levels in your home. The only way to know for sure is to test. This map may differ from the EPA predicted risk Radon Zone Map since it is based on radon test kit results.”

For homeowners who have tested and need to mitigate, other helpful information is provided on the department’s website, including

Ohio Radon Mitigation Data

Summarized by Margaret Henderson

Radon mitigation data for Ohio are presented in a presentation
http://www.eng.utoledo.edu/aprg/radon/concentrations/main.html
created by Ashok Kumar, Charanya Varadarajan, and Suman Maroju from the Department of Civil Engineering , University of Toledo. The project was funded through the Ohio Department of Health.

Records on 17,089 mitigations were examined, which reported 15 different types of systems contractors reported using. Information is available by city/county and year in the mitigation database. (Records with complete information totaled 11,565.)

An on-line presentation about radon, created through funding by the Ohio Department of Health, discusses “Management of Indoor Radon in the State of Ohio.”

Nebraska Radon Program Awareness and Risk Reduction Projects for 2016-2017

by Margaret Henderson

Nebraska has a very high incidence of radon in homes; over half of radon tests in the state are above the EPA recommended action level of 4.0 pCi/L according to the Nebraska Department of Health and Human Services Radon Program. Data reported by county and city shows 73,280 test results with 60% of those being in excess of 4 pCi/L. The highest test result was 282 pi/L. Much of the state has recorded radon levels between 21 and 100 pCi/L, according to the mapping of data through 2013. http://dhhs.ne.gov/publichealth/Documents/RadonHighestResultByCounty.pdf

The Nebraska Radon Program Awareness and Risk Reduction Projects encourage more testing and mitigation. The program supports this mission by awarding grants to non-profit organizations for efforts to increase local awareness about the risks associated with radon exposure and to involve communities risk reduction.
