Why are you arguing about appropriate risk levels when they've already been set by EPA and are being exceeded in these schools?

The risk at 4.0 from a classroom is pretty much zero. Look at the actual statistics and how long they presuppose one is exposed to the room.
The risk at 4.0 is certainly not zero. The risk at 2.0 is not even zero. You're being ridiculous.
Pretty much zero, not actually zero. There is no such thing as actually-zero risk. (I'm not the PP you're responding to.)
If 1,000 people who never smoked were exposed to 4 pCi/L over a lifetime, about 7 people could develop lung cancer. (The EPA says that this risk of getting lung cancer compares to the risk of dying in a car crash.)
If 1,000 people who never smoked were exposed to 2 pCi/L over a lifetime, about 4 people could develp lung cancer. (The EPA says that reducing radon levels below 2 pCi/L is difficult.)
If 1,000 people who never smoked were exposed to 1.3 pCi/L (the average indoor radon level) over a lifetime, about 2 people could develop cancer.

yes. all fun and games unless it is your child!
Plus the research shows that lung cancer is just one problem from smoking and there are so many more health related issues. Give me a break. Its radioactive gas!
