National Action Level 4.0 pCi/L

This is a NATIONAL Action Level

  • i.e. does not vary by state
  • There is no mandate to test in single-family residential dwellings, yet.

There is No Safe Level of Radon Exposure

  • WHO studies show radon risk as low as 2.7 pCi/L
  • EPA also recommends that Americans consider fixing their home at radon levels between 2 pCi/L and 4 pCi/L
  • EPA says most homes can reasonably achieve a level below 2.0 pCi/L and that should be our goal!
