Wow, a load off my mind, I might not get lung cancer from the air in my staircase, if I'm one of those lucky few belonging to "not everyone". As if that's not ridiculous enough a statement from an official agency, it is then followed up by the amazing number of 20000 deaths a year. So the EPA is claiming that radon has similar risk to traffic accidents. Oh, and you get stomach cancer by drinking water. Great.Not everyone exposed to high levels of radon will develop lung cancer. However, radon in indoor air is the second leading cause of lung cancer. About 20,000 deaths a year in the U.S. are caused by breathing radon in indoor air....
...breathing radon increases the risk of lung cancer over the course of your lifetime. Some radon stays in the water; drinking water containing radon also presents a risk of developing internal organ cancers, primarily stomach cancer.
Amazingly, the EPA refers to this "information" as "basic information".
Things everyone should know about radon, huh?

They refer to a NAS report, which already explains much. Still, this EPA website is pretty depressing.
