In Minnesota, what is the minimum acceptable radon level requiring mitigation in a residential property?
A2 pCi/L (picocuries per liter)
B4 pCi/L✓ Correct
C10 pCi/L
DAny detectable level
Explanation
The EPA and Minnesota Department of Health recommend mitigation when indoor radon levels reach or exceed 4 pCi/L. Minnesota homes have a higher-than-average likelihood of elevated radon due to the state's glacial geology. Testing and mitigation are strongly recommended for all homes.
