Dear colleague,
thank you for this pointer. Of course, it does not address the point raised by John Jacobus, who denied that there might be evidence to the contrary - which even is acknowledged as such by the ICRP. 
Can you provide a pdf copy of your paper?
Thank you in advance, Rainer

P.T. Colleagues,

See: Skowronek J., Zemla B. - Epidemiology of lung and larynx cancers in
coal mines in Upper Silesia - preliminary results. Health Physics, September
2003, Volume 85, no 3.
Increased exposure to radon progeny (but still on the level of low doses -
< some mSv/y)) in coal mines increases risk of lung and larynx cancer.

"There is no evidence that increased exposures to radiation have done so
[reduced incidence of lung cancer]."

Dear John:

Of course, whether or not your above statement holds, depends somewhat on
what you consider "evidence". Regarding lung cancer, even the ICRP concedes
that the [LNT] atomic bomb survivor risk estimates do NOT fit into the
picture outlined by epidemiological data from truly chronic low dose rate

"For cancers at some sites there is reasonable compatibility between the
data from LSS and those from others sources. However it is recognised by the
Commission that for a number of sites, e.g., lung, there are significant

RADIOLOGICAL PROTECTION. Draft for consultation. §(104) p. 30 and once more
in annex A, (A13) p. 67)

I attach a PDF file with 6 diagrams showing such significant differences in
data from some of such 'opposing' studies.(If the attachment does not pass
the moderator, I will provide it upon request)

Unless you can provide reasons for ignoring these findings, my
interpretation of these data falsifies your above statement.

Kind regards, Rainer

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."
