Fe-55 in nuclear plant effluents

[VANDERMEYT@detroitedison.com]

I need to know if anybody analyzes gaseous effluent samples for Fe-55.  
Although Fe-55 analysis is not required by generic tech specs for gaseous 
effluents (it is for liquid effluents), Fe-55 is a large fraction of total 
activity in some waste streams. 
 
Please reply especially if you do perform Fe-55 analysis for gaseous 
effluents, and tell me also what the relative dose impact of this isotope is 
at your facility.  You can reply to me (Tom VanderMey, Fermi 2) directly at 
vandermeyt@detroitedison.com.  Or you could post general thoughts about 
whether any nuclear plant should analyze for this isotope in gaseous effluents 
(given that it has fairly low dose factors and is only an internal hazard) to 
Radsafe.
