RE: ALARA



Phil, et al:
 
My apologies!  The quote is on p. 58 of NCRP-121.  But don't be surprised by the blatant contradictions. The following page says "The concept of ALARA, viz. that all radiation doses shall be kept as low as reasonably achievable...has been a fundamental principle in radiation protection for several decades...The concept of ALARA presumes that any increment of radiation dose may produce a proportionate incremental risk...The use of collective dose to calculate risk for purposes of optimization of protection is acceptable and desirable..."

Ted,
 
I could not find the quote in NCRP-136.  Do you have the right reference.  Given the pro-LNT stance of NCRP, it does not seem like something they would say.

Regarding adding up trivial individual doses, NCRP-136 warns (p.58):
The summation of trivial average risks over very large populations or time
periods.has produced a distorted image of risk, completely out of
perspective with risks accepted every day, both voluntarily and
involuntarily.
