Automation of the Radioisotope Accountability System The Radioisotope Service of the Veterans Administration Hospital, Omaha, Nebraska, used a manual system of radioisotope accountability for three years. The procedure which was satisfactory but time-consuming was converted from manual to a fully automated computer system in January, 1963. The program for purchased radioisotopes is written in FORMAT FORTRAN for the IBM 1620 Computer. A second program for maintaining accountability for reactor-created radioisotopes is written in the FORCOM programming language. A minimum amount of bookkeeping is required by the reactor operating staff. The United States Atomic Energy Commission regulations specify that records be kept. This system provides detailed records for each container of radioactive material purchased and/or created in the Triga reactor indicating the amounts received, used, and/or transferred to the health physicist for disposal. Consolidated records contain total amounts received, used, and/or disposed of for any specified period of time. Purchased radioisotopes are reported in millicuries; reactor-created radioisotopes in microcuries. CACM February, 1965 Lahners, E. L.
