[ RadSafe ] Re: RadSafe

[John Jacobus]

Dr. Sanders,
Thank you for responding and posting the attachments. 
As I interpret your presentation, there is no real
evidence that radiation prevents lung cancers in
smokers, noting the exclusion of radon exposure?  As
you indicate: 

"A low-dose protective apoptosis-mediated (PAM)
process, limiting potential cancer formation, may be
activated by low-dose, low-LET gamma or x-radiations
(Scott 2006a,b,c). Low dose radiation may stimulate
apoptosis of cells transformed by chemical carcinogens
(Mitchel et al. 1999; Sakai et al. 2003). Low dose
ionizing radiation may enhance the elimination by
apoptosis of cigarette-induced transformed pulmonary
cells, thus decreasing lung cancer risk (Scott
2006b)."

Interesting, but I did not see any data to support
this conjecture.

Personally, I try to say out of radon issues.
