Radon is the second leading cause of lung cancer worldwide. High levels of radon gas occur naturally in Maine soil and water, and can move up into a house from the ground. The house then traps the radon in the air inside. Radon gas can also dissolve into well water, which is then released into the air when you use the water. Any house can have a radon problem. It doesn’t matter if it’s old or new, or where it’s located. The only way to know if your house has a problem is to test. Simple air and well water tests can show whether home radon levels meet state and national safety guidelines. Landlords in Maine are required to test their rental properties.
