[ RadSafe ] Re: Lung cancer reduction

[John Jacobus]

Dr. Luan,
If you have serious concerns about the high incidents
of lung cancers, I would think that you would foster
the idea the people should stop smoking.  Studies have
shown the individual who stop smoking have reduced
incidents in lung cancer.  There is no evidence that
increased exposures to radiation have done so.  

Also, as WE discussed several years ago, your
statements on reduction of cancers in Taiwanese
apartment dwellers was at best an incompete report. 
At worst, badly flawed.  There has been no further
study of these people, as opposed to the Atomic Bomb
survivors.  In your work was of limited scope.  

Maybe this is why many professional radiation
scientist consider this to be a "wild story."
