Free radon test kits
Most states run a radon program funded by federal and state grants, and many of them mail residents a free short-term test kit, usually in January during Radon Action Month, sometimes year-round. Supplies are limited and windows open and close quickly. This page tracks every state; each row links to the state’s record, its counties, and its official source.
