Should you test your indoor air for radon? Should you test your private well water for radionuclides?

Interactive Geological Map
The North Carolina Geological Survey has created an interactive map for those wanting to explore the geological formations in each county that contribute to increase radon, uranium and other radionuclides.

Radon is a gas that is naturally present in rocks and soil in North Carolina. It is created when uranium in the ground decays. Some building materials can also have uranium, and the only way to know if radon is being released indoors is by testing the air. Radon itself cannot be seen, smelled, or tasted.
The rock and soil underground is different throughout North Carolina. Certain counties in North Carolina have a geology that is more likely to contain radionuclides. It is possible that private well water may flow through the radionuclides and transported to your home.
Owners of buildings built with certain materials, such as large buildings and mid- high-rise condominiums, should consider testing the indoor radon level. The CDC reports that "any buildings built with sandstone, concrete, brick, natural stone, gypsum, and granite contain naturally occurring radioactive elements like radium, uranium, and thorium." The only way to know if these materials increase indoor radon levels is by testing for radon.
Testing Private Well Water
It is important to test the air in your home, apartment, or commercial building for radon every two years. Radon is a gas that can be harmful and cause lung cancer if it builds up in your indoor air.
If your indoor air radon level is between 2 and 3.9 picoCuries per liter, the NC Radon Program recommends you consider hiring a certified radon professional. They can install a system that will lower the radon level and make your air safer to breathe.
If your indoor air radon level is equal to or higher than 4.0 picoCuries per liter, the NC Radon Program strongly recommends that you hire a certified radon professional. They can install a system that will lower the radon level and make your air much safer to breathe.
