RE: Po-210 in tobacco

["Christoph Hofmeyr" <chofmeyr@nnr.co.za>]

Bjorn, Radsafers,

As I tried to indicate in a previous contribution, I would really like

to see the amount and variability of e.g. Polonium-210 in tobacco

quantified.  Comparison with e.g. radon exposure should make some sense,

except if very strong synergisms are at work.

Own musings.

In 1977 (approx) it was stated that cigarette smoke contains at least

about 

20 000 different chemical substances that are harmful to humans. I find

it 

difficult to single out any one of those substances as responsible for

lung 

cancers - or is there a shortcut to get the 50 % for Po-210 answer? And

in a 

sense - who cares (OK we want to know about radiation risks) - when the 

bottom line is "don't smoke!".



My personal ideas only,
