Idaho Radon Levels Presented in Mapping Program Reaching Thousands of Viewers

by Margaret Henderson

The Idaho Department of Health and Welfare presents radon date in a mapping program that allows users to examine radon data. The map, created December 2016, was last update July 2018, and has had 24,748 views.

The map, divided by county lines, indicated percent of high radon levels based on test results. Information presented includes:
• Zip code
• County
• Number of tests
• Number of tests high (greater than 3.9 pCi/L)

For instance in Ada County, 300 test results were collected and 12% exceeded the 3.9 pCi/L level.

Much of state is included in the Zone 1 designation by USEPA, having the highest potential for excessive radon (greater than 4 pCi/L). Fifteen counties are included in this zone, covering much of the state’s area.
