Test for Radon

1. Short-Term Radon Test

Depending on the test you choose, you’ll need to leave it out in your house for between 2 and 90 days. The test is sent to a lab for processing. If the radon levels in your home are at or above 4 pCi/L (picocuries per liter), contact a radon mitigation company.

2. Long-Term Radon Test

A long-term test provides a more complete picture of seasonal changes in radon levels. Long-term tests often consist of polycarbonate sheets that are left in the lowest level of the home for more than 90 days. The alpha particles emitted by radon gas leave tracks behind on the sheets. More alpha tracks signal higher levels of radon in the home.

3. Continuous Radon Test

Another way to test for radon gas and track the air quality in your home is to use a digital radon monitor. These monitors measure the alpha particles in the air using a special sensor. They continuously take readings and display pCi/L readings on a screen.

4. Well Water Radon Test

Radon can build up in well water. When you use well water in your home—particularly heated well water—the radon can dissolve and move into the air. This can lead to temporarily higher radon levels when large quantities of water are used, such as when taking a shower.
