Leave if you wish.  However, there are many who say

that the issue of hormesis is not relevant to public

health policies.  And that is the central arguement to

position.  



1.  Stat Med. 1989 Feb;8(2):173-87.  

"Issues in analysing the effects of occupational

exposure to low levels of radiation." Gilbert ES.



2.  Regul Toxicol Pharmacol. 2002 Jun;35(3):414-28.   



"Hormesis and high-risk groups."

Calabrese EJ, Baldwin LA.



3.  Annu Rev Public Health. 2001;22:63-7.  Hormesis:

implications for public policy regarding toxicants.
