Hey Tamar,

>Yeah, I know. But when you actually start digging (as my husband needed to, for business reasons), it turns out there's no good research on this. He actually had this discussion with someone at the state DEP and the guy send him a whole pile of material, but admitted that none of it was actual studies of whether small concentrations of radon, such as those found in homes, cause lung cancer.

There's a lot of this faux science going around. Second-hand smoke, for example. Most state's smoking bans and a good number of federal laws are based upon the assumption that seciond-hand smoke is hideously bad for you. Now, logic and common sense would dictate that second-hand smoke IS bad for you, or as George Carlin put it, you wouldn't want to eat a second-hand ham sandwich. Having said that, there are no thorough scientific studies on just how bad it is. So all these laws are built on assumptions without hard fact.
