Attention: Division of Liconemg and Regulatica Gentiamens The Rhode Is1cnd Atcmic Energy Consission (RIAEC) herab7 submits for approval of the U. S. Atcaic Energy Ccmnocion (USA 20) infornticn to establish an ataoophoric dilution factor of 10 se:/n3for determining the permissible average concentration of radiotetivu offluent from the reacter effluent diuposal stack which is 22 inches in diaator and 11$ foot hi; hor t than the surrounding terrain. Such a dilution factor &pplicd to the disposal of cirborne radioutin c:sterLd is eufficient to enaure tJ st the yccr3y eversge concentration of such i n:aterials at all points in unrestricted aron around tho stack, whica cuald be cccupied by individush will not cxceed the mxinam permissible, non. occupational concentrations estub]iched by the USAE04 The inforation which fo11cma 2dicates that dispceal of airborno radioactive ut,orial from a stack which pr<nidce a dilution factor of 10 sec/m3 can to actoly permittod.
