Radon in Air
Short Term Tests*. Short-term tests are conducted for 2 days to 90 days, depending on the device.

*If you are involved in a real estate transaction, or want results quickly, a short-term test is recommended.

Long-term tests remain in your home for 90 days, up to one year. A long-term test will give you a reading that is more likely to tell you your home's year round average radon level.

Radon in Water
The EPA recommends testing for radon in water if the water supply is from a private well or from a public water system that mixes well water with surface water.
