That is an understatement. I agree. I will tell you that a lot of people finish basements and put bedrooms in them, which people spend a lot of time in. This increases the risk exponentially. I have tested basements for radon that had negligible readings and those that exceeded 100 pCi/L, which is an insane number, and a lot of them in hot spots, typically a lot of rock, routinely in the 20s and 30s. Add to that a well instead of public water, and you compound the problem. People spend anywhere from 2,500 to 3,200 hours annually in bed. For those in a high radon environment, that is a lot of exposure.We are exposed daily to strong carcinogens that I believe are far more detrimental to our health.
That is a free-market issue, not a code or science issue. I believe the levels found during repeated testing should determine whether the system is passive or active. Then you can repeat the testing to determine effectiveness.Correct whole-house ventilation would eliminate this issue and resolve many others simultaneously for less money.
Unfortunately, scare tactics have been used to embellish this issue. I have seen companies that supposedly are industry experts charge exorbitant amounts of money to cut a hole in a floor corner ad piping with a fan to the outside.
HRV can dissipate up to 50%.. so turns a 7pico to 3.5Correct whole-house ventilation would eliminate this issue and resolve many others simultaneously for less money.
