statistics question (OT)

I was really wondering if one could back into this. That would require some assumptions which (from your reference) are in hindsight impossible to get right.

Thanks for the ref., though. I find it interesting that the EPA cutoff for remediation in homes -- 4 picoCurie/liter -- which was specified many years ago (at least 20) is still their standard, even though they've only more recently (this report being 7 years old) come up with an estimate of the probability of Radon causing a lung cancer resulting in death. This is a function of radon exposure (and thus a function of radon background in enclosed spaces).

Biology is so much more complicated than the physical sciences, since it's so difficult to control the variables. This is likely a/the major cause of faulty results (but definitely not the only cause).
