Thanks for sending, Chrys. Thanks to the researchers for this work. It is definitely worth looking at for some perspective. For example, readers will see that the fraction of lung cancer deaths in Korea attributable to radon tends to be in a higher range than that usually cited for the U.S. Also that mitigations to 2 pCi/L would collectively save almost twice as many lives as mitigations to 4 pCi/L (On a quick read, I didn't see that the study attempted to reflect what mitigations usually achieve, which would typically be under 2 pCi/L, and well under 4 pCi/L on average, so the values for deaths and YLL averted may be underestimates.) Also interesting to note that the gender relationships for smoking are quite different than what we're used to in the U.S.
