AW: [ RadSafe ] AW: Gasteiner Heilstollen for holiday!?

[Christoph Köstinger]

Dear Rainer,

I think all these data are probably not significant as the overall
population in Bad Gastein and Bad Hofgastein (both 6.000 inhabitants) is not
very big. At least we were told several times by epidemiologists.

At least we don´t have any fear about lung cancer and I live there.

Best regards


Christoph Koestinger,

John:

 

Taken at face value you might speculate that increased (mainly) Radon
exposure decreases lung cancer incidence (Badgastein vs. Salzburg). Yet the
rather short paper does not present sufficient facts to make that case.
However, I reproduce a reference which I gave you already recently which
many years ago found already genotoxic evidence about what an underlying
mechanism might be.

 

"It is suggested that the shape of the dose-response curve at these very low
levels of radiation [at Badgastein] may result from the induction of repair
enzymes." (already in 1979!)

Pohl-Rüling J, Fischer P, The dose-effect relationship of chromosome
aberrations to alpha and gamma irradiation in a population subjected to an
increased burden of natural radioactivity. Radiation Research 80(1979)61-81

 

BTW, Pohl-Rühling belongs to the luminaries in her field.

 

Regards, Rainer

Ranier,
Would you then conclude that increased annual doses of radiation do not have
a noticable effect on cancer rates?
