Maine Radon Homepage

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.

Radon Tip Sheets

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 leveles 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.

The Maine Radiation Control Program's Radon Section is taking requests for a free inspection of radon mitigation systems that have been installed by a state-registered mitigation contractor or by a builder during construction.
