The Radiation Control Program provides, free of charge, information packets containing information on different aspects of radon. We also register radon service providers (laboratories, contractors, and testing companies) that have a proven level of training.

Testing and Mitigation
The State advises you to take action to reduce the radon level in your home's indoor air at 4 pCi/L, but consider reducing levels between 2 and 4 pCi/L. The current advisory level for radon in your home's water supply is 4,000 pCi/L. At levels of 4,000 pCi/L or higher you should consider action beginning with reviewing your total radon risk (from radon in air and water). As your radon level in water gets closer to 10,000 pCi/L, you need to more strongly consider installing treatment.
Under Maine law, only the owner or occupant of a residence or someone registered with the state to provide these services, may test for radon, install and/or advise on the installation of a radon reduction (mitigation) system. If the home or residence is for sale then the owner or occupant cannot test for radon or install a system to reduce it, the testing and mitigation of properties for sale must be done by a registered radon service provider.
