Radon Data

New York State Department of Health - Center for Environmental Health - Bureau of Environmental Radiation Protection
Provides data on all radon testing conducted from 1987 and forward, through the New York State Department of Health Radon Test Kit program. Data includes residential and school tests results and are available by Town and County in New York State.

Data type: Radon test data
Timeframe: 1987 to 2017
Geographic Coverage: Town, County
Comments: Tables present average and maximum radon test values as well as the number of buildings tested for radon. In some geographic locations, only a few radon test results are available from using the NYS DOH Radon test kits; therefore, care must be given in the interpretation of the data. While these statistics are useful to show potential radon levels for a town or county, the DOH radon program advises that the best indication of radon levels at a particular location can be determined by testing the building or home. Radon test kits can be requested from the DOH.
