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
