Value of a Person-Rem

["John R. Laferriere 671-8316" <John.R.Laferriere@dupontpharma.com>]

Radsafers:
I'm trying to roughly quantify the dollar value of a facility redesign 
project attributable to the estimated reduction in person-rem that will 
result from the upgrade.  What I'm looking for are references that 
mention specific dollar values per person-rem saved, for occupational 
exposures currently in the 1-1.5 rem/yr range for an individual worker.
Alternately, if there is a value currently widely used within the nuclear 
industry, but which doesn't have the endorsement of any specific body, 
that would be of interest too.

I have looked through ICRP publications and found values ranging from 
$1000/person-Sv to $100,000/person-Sv ($10 to $1000/person-rem) 
referenced (ICRP 37).  These numbers seem unrealistically low to me.

I have heard mention of an NRC endorsed value of $2000/person-rem, but 
have no idea whether this is truly an official number, and if so where in 
writing it appears.

A search on Quest turned up a paper in Radiation Protection Management 
quoting a value of $5000/person-rem, but without any reference mentioned .

I assume this information would be of general interest to radsafe, but feel 
free to reply directly to me, and I will be happy to summarize those posts 
later.

Thanks in advance for any numbers or references you may have.
