Re: Basis for DOT Contamination Limits

["tom_dixie" <tom_dixie@email.msn.com>]

There was a publication by LANL (J.W. Healy) in September of 1971 titled
"Surface Contamination: Decision Levels"  The publication number is LA-4558
and I go my copy through NTIS.   The document was completed under contract
to the AEC.  You cannot pull the limits used by NRC or DOT directly from the
publication, but this was probably one of the supporting documents for the
"limits".  This document provides decision levels for about 180
radionuclides on clothing and skin for workers and for members of the
general public.
