Re: radiotoxicity of various nuclides

[John Harvey <harveyj@mcmail.CIS.McMaster.CA>]

The Atomic Energy Control Board of Canada has a document entitled "Report 
on Derived Working Limits for Surface Contamination" ACRP-7. The Public 
Relations Office can be reached at 
/I=S/S=HAMEL/O=AECB.CCEA@mhs-atomcon.attmail.com 
and they will send you a copy if requested. This document provides the 
methodology to calculate limits for individual isotopes based upon their 
Dose Conversion Factors.
