Re: Emergency Doses Allowed

["Rey The_Fed_Man" <rad_con@hotmail.com>]

Steve, et. al.

The U.S. Department of Energy currently has dose guidelines for 
accidents and emergencies in the regulations (10 CFR 835.1302)  The dose 
limits run from 5 rem for all emergencies to >25 rem for lifesaving of 
large populations.  25 rem is the dose limit for "lifesaving or 
protection of large populations."  There are other caveates too numerous 
to mention here.

58 FR 65483 makes it very clear that these values are only guidelines 
and they have been removed from the proposed revision to 10 CFR 835 --- 
I'm not exactly sure why.

Don't usually add disclaimers to what I say, but .....
The facts I mentioned above are not mine ... just the facts.
