Release Concentrations

[Peter Fundarek <p.fundarek@utoronto.ca>]

Hello,

Up here in the Great White North, we are grappling with a 
new regulatory document called Consultative Document 123 
which deals with the concept of generic release 
concentrations.  The AECB, our regulatory agency, has 
developed these generic maximum release concentrations for 
licensees who do not develop their own derived emission 
limits.  I am looking at the impact of this new document on 
a potential for a delay and decay facility in the 
university.  I know that such facilities are rather common 
in the U.S. and was wondering what your limits for release 
to landfill are for the isotopes listed below.  I have 
included what the proposed C-123 limits are:

P-32	MRC 30 Bq/kg 	(0.8 nCi/kg)

S-35	MRC 200 Bq/kg 	(5.4 nCi/kg)

I-125	MRC 2 Bq/kg   	(54 pCi/kg)

I-131	MRC 1 Bq/kg	(27 pCi/kg)

Cr-51	MRC 1000 Bq/kg	(27 nCi/kg)

Thank you in advance for your assistance.
