Radon Testing
The Issue: Radon in air
Radon, a naturally-occurring radioactive gas, is the second leading cause of lung cancer and the number one indoor air pollutant in the country. Average outdoor concentration of airborne radon in Maine is 0.5 to 0.8 picocuries per liter of air (pCi/L). Maine Center for Disease Control (CDC) recommends that mitigation should be considered when the indoor concentration of radon in air is 2.0 pCi/L or more but is dependent on how the space that was tested will be used. For more information, contact the CDC https://www.maine.gov/dhhs/mecdc/environmental-health/rad/radon/hp-radon.htm. The Environmental Protection Agency (EPA) recommends mitigating when the indoor concentration of radon in air is 4.0 pCi/L or more. One in three Maine homes will have a problem with elevated airborne radon levels.
The Issue: Radon in water
Radon in the soil dissolves into the groundwater and may be present in well water. Radon gas escapes readily from running water and becomes a pollutant in your home’s air. The problem arises when you are running water in your shower, dishwasher, washing machine, or other water-using appliance. Maine CDC recommends consider mitigation of radon in water if levels exceed 4000 pCi/L but is dependent on the radon in air concentration. The EPA recommends mitigation of radon in water for levels exceeding 10,000 pCi/L.
