[ RadSafe ] Why hormesis happens--

[Jerry Cohen]

Gazillions of $$$$ have been spent on research to determine the harmful effects 
of low-dose radiation and the  mechanisms causing these effects. As I see it, 
the main result of this effort is the determination that further study is 
needed.
Many, including myself, believe that the effects of low-dose radiation exposure 
are more likely to be benefical in nature (i.e.,  Hormesis). Although there is 
much statistical evidence to support radiation hormesis, little, if any, study 
has been directed toward learning what mechanism(s) would cause  hormesis.  As 
is the case in the effort to gain an understanding of mechanisms leading to 
harmful effects, it might be reasonable to inquire what would cause beneficial 
effects to result from low-dose radiation exposure. One theory holds that the 
free-radicals generated cause increased oxidation levels in tissues which 
somehow confer protection against many disease processes. Research to 
investigate this theory is currently being conducted at Ben Gurion University in 
Israel. As I understand, results, to date, are promising but inconclusive. I am 
not aware of any other programs to investigate possible mechanisms behind 
radiation hormesis. If anyone has such information , I would appreciate learning 
about it.

Maury, I hope you do not see the following (tongue-in-cheek) question as
insensitive to your plight - I truly sympathise.
The healthy living fraternity often has it on about the importance of eating
foods containing anti-oxidants, the more the better. "High in anti-oxidants"
seems to be one of the best qualifications; it might even help to counteract
free radicals due to radiation, etc.
I often wonder how much of these healthy foods one can eat before you
suffocate, seeing oxygen is the most pervasive oxidant in one's body?
