Re: EPA Action Level for Radon

[RADSRVS@aol.com]

Tom:

Although EPA continues to use 4pCi/L as an "action level" the Agency has 
clarified that radon levels lower than 4pCi/L still pose a risk and thus, EPA 
advises that the public may wish to consider reducing levels to between 2and 
4pCi/L

EPA's threshold for action (4pCi/L) is not a health-based standard; rather, 
its based upon technology available in the 1970's to reduce radon in homes 
contaminated with uranium mine tailings.
