There are two general ways radon detector kits are used. Which kit to use and how to run the test depends on your reason for testing.
A first time or screening test to determine if radon is present within the home should be done with a short-term carbon canister kit. Place the radon test kit in the lowest “lived in” portion of the house. The kit instruction sheet will list the duration of the test period and where to mail the kit for analysis. If the amount of radon found is from 4 to 10 picocuries per liter, use a long term or alpha track radon test kit to verify the initial results. If radon levels exceed 10 picocuries, re-do the short-term test to verify the initial results.
Homeowner Testing Flowchart
Close all windows and doors on all floors of the house 12 hours before beginning the test and throughout the test period. You can go in and out of the house, but keep it closed up as much as possible during the test.
Use two short-term radon detector kits exposed at the same time or 2 short-term tests run one after another. Place the radon test kits in the lowest portion of the house that is used for living purposes. The kit instruction sheet will list the duration of the test period and where to mail the kit for analysis.
