The EPA recommends all homes be tested for radon and taking action if the radon level is 4 picocuries per liter (pCi/L) or higher. Levels lower than 4 pCi/L may still be harmful.
Radon issues can be fixed and even higher levels can be reduced to acceptable levels.
Testing is the only way to determine if your home's radon levels pose a threat.
