Re: AW: "The Bell Tolls for LNT"
The LNT has never been a regulatory tool. ALARA is a
regulatory tool.
The LNT is a theory to evaluate the unknown risks of
radiation at low doses based on values observed at
high doses. It may be used to justify proposals for
regulatory limits or recommendations for constraints
as used by the ICRP, it never had the impact in
regulations that ALARA does. As a scientific theory,
I have come to believe that it leaves much to be
desired. It was based on extrapolation of datapoints
from known data sets to unknown areas. That is
reasonable to do in physics, but not biology and over
several decades of doses.
So, the question is if the LNT "dies," will
regulationary restrictions change? If no adverse
risks have been shown to exist below 100 Sv (10 rem),
http://hps.org/documents/radiationrisk.pdf, how come
regulations have not been relaxed? Can anyone cite a
reduction of safety standards for another toxin? (I
am sure someone will.)
