Free radon test kits in Washington

Washington has free kits and asks something in return. The health department says its supply is limited and asks that you only request a kit if you are actually going to use it. That is a fair request and worth taking seriously, since every kit sitting unused in a drawer is one another household did not get. Once you have it, the test is a few days in the lowest room you spend time in. Order through the Department of Health. If the supply has gone, short term kits are sold in hardware stores.
