[ RadSafe ] radsafe, exposure dose

[conrad]

you will, of course, have to correct for the finite size of the room, 
depending on the isotope this correction may be significant; I could put you 
in touch with a consultant who could do a professional analysis for you, 
unless of course Dr. Cohen wants to do it.  if you dont have the icrp 30 
docs, fgr reports from epa are free from the web site.
