According to the Epa, at What Level Does Radon Become a Health Concern Requiring Mitigation?

If the radon level in a residence is 4 pCi/L (picocurries per liter) or above, the EPA advises that it be corrected. Because there is no known safe limit of radon exposure, the EPA also advises Americans to test their homes for radon levels between 2 and 4 picocuries per liter. 29.11.2021

You might also be thinking, What is the EPA action level resulting from a radon test?

pCi/L = 4 pCi/L

Similarly, What is an acceptable level of indoor radon?
