Dear Greg
Very good point!
See: http://en.wikipedia.org/wiki/Hormesis
and
http://www.ingentaconnect.com/content/tandf/bher/2001/00000007/00000004/art00016
This latter reference
Analysis of a Hormesis Effect in the Leukemia-Caused Mortality Among
Atomic Bomb Survivors
confirms the existence of the hormesis effect.
Best wishes,
Kevin
