نبذة شخصية:	Discover radon, how it affects lung health and wellness as well as what you can do concerning it. The only dose-effect connection readily available are those of miners friends (for a lot greater exposures), subjected to radon. Studies of Hiroshima and Nagasaki survivors are much less useful (the direct exposure to radon is persistent, local, as well as the ionizing radiations are alpha rays). Furthermore, the smoking is a substantial confounding factor in all miners' researches. A questionable epidemiological study, unexpectedly showing reduced cancer cells threat vs. radon domestic exposure (5 pCi/L ≈ 200 Bq/m3).
