How about using effluent concentration limits in Appendix B Table 2 of
-10CFR 20?(or equivalent agreement state regulations). These concentrations
are for release to unrestricted areas . 
  
BTW, I dont believe that "Disposal of RAM" in concentrations below the
regulatory limits  is  the same as "transfer of  licensed quantities of RAM".
