Canadas level is 5 pCi/L. Why does the EPA set ours only at 4.0 pCi/L?
I get asked this question all the time. First of all, Canada’s level was 8 pCi/L. It was just reduced recently. Realize that have a socialist form of government. When a home tests high (above 5) their government has to pay for the Radon mitigation system to be installed. Their action level is not based on health or risk; it is based on finances. The Canadian government can not afford to set the level any lower. Remember a level of only 4 pCi/L for 8 hrs a day is the same as 200 chest X-Rays a year. The first home that was ever mitigated in the US was able to brought down to a level of 4 pCi/L. This was after the home was tore apart and new fill was bought in. This home sat on a main Uranium deposit. It had tested in the thousands of Pico Curies. That’s why our level is at 4 pCi/L. Most homes can be lowered below 2 pCi/L if not below 1 pCi/L. Outside ambient levels are at 0.4 pCi/L.
