Rhode Island Radon Information
Radon can be found in homes throughout Rhode Island. Because it is colorless and odorless, testing is the only reliable way to know the level in a given home.
Radon in Rhode Island homes
Radon levels vary from home to home — even between neighboring properties — because the gas moves through soil and enters buildings through the ground beneath them. Housing stock across Rhode Island is diverse, from older homes with stone foundations to newer construction, and any of these can have elevated indoor radon.
Testing is the only way to know
A radon test measures the actual level of radon in the air during the test period. General maps and averages can be useful background, but they do not replace a test on the specific home in question.
Radon in real-estate transactions
Radon testing is a common part of Rhode Island real-estate transactions and is often requested during the buyer's inspection period. Sellers sometimes choose to test before listing so results are available to prospective buyers.
