A radon test kit is an effective and inexpensive way for you to determine the radon level in your home. Radon gas tests basically fall into two categories...
A short-term device is most commonly used to determine the initial level of the home. If the results of a short-term test are in the 4pCi/L to 10pCi/L range the EPA suggests that a follow up long-term test might be desired to access the average long-term level of the home. But if time is a factor another short-term testing kit may be used to verify the results of the first radon test.
Radon gas tests available for the public are charcoal canisters, alpha track, and charcoal liquid scintillation. These radon kits are readily available and inexpensive.
If you are purchasing a home, a radon test should be an important part of the home inspection process. In this case, a radon measurement provider will be needed to perform the the test as a neutral party to the real estate transaction. A high radon level should not be a deal buster, as radon reduction techniques can reduce levels to very acceptable levels.
