Supplemental Radiological Criteria

[Alan Jackson <AJACKSO1@SMTPGW.IS.HFH.EDU>]

Radsafers,

I just received an NRC mailing regarding Radiological Criteria for License
Termination (FR Vol 63 No 222 p 64132).  This document contains a table
with some surface contamination screening values for common
radionuclides.  These numbers are much higher than I have seen.  I don't
doubt that these make sense based on risk but I'm (pleasantly) shocked
to see them coming from NRC.  Does anyone actually use these for
release values (e.g. Tritium 1.2 E8 dpm/100 cm2)?

A related question...does anyone have similar numbers for other common
research nuclides?
