Description/Abstract:
This report concerns the Health Physics Progress Report for January 1, 1953 through June 30, 1953. Approximately twenty-five percent of mercury air analyses exceeded the MPL of 0.1 mg/M3 because of the rapid expansion of mercury handling facilities. Completion of hoods and modification of process methods resulted in a reduction of general air contamination in the normal uranium machine shop. Elevated air concentration in the normal foundry resulted from production changes and ventilation failures. Contamination and/or radiation inspections are made of all shipments of materials or equipment leaving Y-12 by common carrier to comply with regulations, and results accompany the shipping invoice. A total of 379 persons were regularly issued one or more film meters. Radiation hazards in connection with the recovery of uranium from Arco salvage material were investigated, and sampling indicated forty-three percent of the active material (Ru-106) was carried away as waste, three percent remained in the cycle, and fifty-four percent accompanied the product material. The Health Physics Department needed a gamma spectrometer and beta-gamma counters continuously available for air sample counting as part of a program, and these were installed. A personnel exposure study was done in the 9212 B-1 Foundry and found the greatest radiation problem was created when long-stored rods were used during casting. New electroplating equipment was designed and described as a simplified procedure developed for analyzing micro-quantities of enhanced uranium in urine. Work has continued on analysis of uranium excretion curves of twenty-one employees. It was surmised that retention of uranium in humans is different from that in small animals which is important from the standpoint of internal radiation delivered to various organs by stored uranium. A kinetic study is being applied to excretion data on humans who were injected with uranyl nitrate hexahydrate. Since the excretion is not due to elimination of uranium stored in the lung, the lung may be eliminated from the model. Tables and figures are included in the report.
