From page 1... ...
The present practice of using 55 gallon steel drums as disposal canisters containing the waste mixed with concrete is estimated to provide containment of approximately 10 years, during which time radioactive decay will have destroyed all radioisotopes (based upon Oak Ridge National Laboratories current rate of production and shipment) to below hazardous levels, with the exception of Sr 90, Cs 137, and possibly Co 60.

From page 2... ...
The return of radioactive wastes to man by ingestion of contaminated marine food products is considered to be the most likely potential source of hazard that could result from disposal into coastal waters. An estimate has been made of the maximum permissible concentration of each of several radioisotopes in sea water, below which contamination of marine food products will not lead to greater than allowable intake by humans whose sole source of protein is fish.
