Abstract |
Brief mention is made of techniques now in use for determining radioisotope hazard. A study was made of data available from the Operations Division, Oak Ridge National Laboratory on radioisotope shipments. Since the number of curies of each radioisotope shipped are known and the maximum permissible concentration for that radioisotope has been suggested, the volume of water required for dilution to the tolerance concentration could be determined. These computations, which were based on several stated assumptions and included the effects of decay, show that there is immediate need for setting standards and procedures for the safe handling and disposal of strontium and perhaps other long-lived radioisotopes.
