Tracking radon data in a standard way over time can help us identify areas that need more testing to provide a more accurate estimate of radon exposure in that locale. Every home should be tested for radon so the individuals living there can see if their home has elevated radon levels and take steps to reduce it, if needed.
The Tracking Network has radon testing data at the state and county level for most of the continental United States. The data on the Tracking Network come from some Tracking Program-funded states and several national radon testing laboratories.
Radon Test Data from Labs
This indicator provides radon testing data at the state and county level for most of the continental United States. National radon testing laboratories provide these data to the Tracking Network. Data available include number of buildings tested; number and percent of pre-mitigation* tests by radon level; median pre-mitigation* radon levels in tested buildings; and maximum pre-mitigation* radon levels in tested buildings.
Radon Test Data from States
This indicator provides radon testing data at the state and county level for some Tracking Program-funded states. Individual states provide these data to the Tracking Network. Available data include number of buildings tested; number and percent of pre-mitigation* tests by radon level; number and percent of post-mitigation* tests by radon level; median pre-mitigation* test levels of radon; and maximum pre-mitigation* levels of radon.
* All pre-mitigation data include those test results not designated as pre- or post-mitigation.
Analyzing, collecting, and disseminating radon testing information is the first step to developing policies and educational resources that can help prevent the harmful health effects related to elevated radon exposures. For example, tracking radon data in a standard way over time can help us identify areas with low testing that might have high levels of radon. These data can inform planning and implementation of public health actions for areas with the greatest need
