[ RadSafe ] Why hormesis happens--

Sun Aug 7 17:53:47 CDT 2011

Might it be reasonable to consider that a lot of surplus meaning may 
very well attach to radiation hormesis? After all, light, heat, and 
sound are not nearly as pervasive as the radiation we label ionizing. We 
have a much greater depth of understanding the effects of the other 
radiations. As our understanding of the effects of ionizing radiation 
increase, might it not become just as acceptable and just as subject to 
prediction and control as the others? If this should be the case, there 
would be little need for the hormesis construct ...  just wondering.
Best,
