TRUMP WANTS THE EPA RADON PROGRAM CUT. SO DO SOME SCIENTISTS"The issue here isn't whether radon causes cancer. It does, certainly. But scientists can only prove that radon is carcinogenic at high doses. Like, rates typically found in mine shafts, not suburban homes. Critics say the EPA's method for establishing low-dose radon risk assessments is simply unscientific. Some even go so far as to say low doses of radiation might help your body fight cancer. Follow that logic through, and they say the EPA's low dose radon risk assessment could actually be harming people."
