Note: If you are a former smoker, your risk may be higher.
ACTION LEVELS: 4.0, 2.7, 2.0 pCi.L 4.0 pCi/L Achieving below the USEPA action level of 4.0 pCi/L can be accomplished for virtually any home. Older homes can present challenges due to construction practices when they were built and in special cases the amount of reductions achieved by mitigation can become a question of expense versus benefit.
2.0 pCi/L The USEPA recommends to consider action between 2 and 4 pCi/L since no exposure is safe. This guidance intends that one seek the lowest exposures possible. However, around about 2.0 pCi/L and lower, the lower limits of sensitivity for most test devices has been reached. Errors up to 300% have been seen to occur for some devices. While testing might often indicated less than 2.0 pCi/L (especially after mitigation), accurate verification for concentrations of less than 2.0 pCi/L is not truly feasible. 0.7 pCi/L Outside air anywhere on earth. This is so low that even the best equipment scientists use can only estimate between 0.4 to 0.8 pCi/L.
