Idaho Tracks Radon Testing Data per Goal of the Cancer Strategic Plan

Idaho Comprehensive Cancer Strategic Plan 2016-2020 lists radon reduction as a Prevention Goal. See the plan at

Goal 5: Reduce cancer risk related to environmental carcinogens, addresses radon with the objective of increasing the proportion of persons living in homes that have been tested for radon.

Strategic actions include:

· Implement evidence-based policies, programs and systems changes to share information among the public, researchers, regulatory agencies and industry about environmental carcinogens, specifically radon.

· Advocate for evidence-based epidemiologic and environmental monitoring and research across the life course (in utero and childhood, workplace, and multi-generational exposures).

· Improve health professional knowledge, practice behaviors and systems support related to known and emerging environmental carcinogens.

Measurement goals are:

Measure 5.1 Percentage of adults living in households ever been tested for radon (age adjusted to the year 2000 standard population)

Baseline 20.7%

Target 28.4%

Idaho Department of Health and Welfare has been tracking this data and recent mapping by is available online as “Home Radon Test Results by Zip Code, ” updated Jan 31, 2020.

Idaho home radon test results by zip code are displayed as percent of tests greater than 3.9 pCi/L, which represents the recommended level for mitigation. Filters allow for examination of testing data, including number of tests in particular areas.
