Description/Abstract:
This document contains the Health Physics Progress Report for July 1, 1953 through December 31, 1953. Routine air sampling continued on uranium, beryllium, and mercury handling operations. Other contaminants were sampled to determine the degree of hazard associated with specific operations. Approximately 35 percent of mercury air analyses exceeded the MPL of 0.1 mg/M3. A large number of analyses exceeding the MPL were obtained either in research and development areas or production areas when a new process plant was being started. Uranium general-air analyses indicated adequate control, since only 5 percent exceeded the MPL of 70 d/m/M3. The high percentage of uranium breathing-zone samples exceeding the MPL occurred because the sampling program was concentrated on operations known to lack effective control. Due to changes and additions being made in air exhaust systems, greater emphasis was placed on stack sampling. The Cockcraft-Walton Linear Accelerator was installed in Building 9207 but has not created a serious Health Physics problem. A total of 415 people were regularly issued one or more types of film meters. The new electroplating unit for analyses was completed and installed. Progress has been made in constructing a dual-channel continuous alpha air monitor which draws air through each of two moving filter tapes, output is recorded, and air contamination above background is the difference of readings. In a preceding report, a kinetic study (included lung in the model) of the distribution and excretion of uranium failed in the duplication of an average excretion curve determination on 21 employees. As a result, a study was made of the excretion of uranium following an intravenous administration thereby eliminating the lung as an organ of storage and supply to the blood and on to the urine. Known amounts of U (VI) were injected intravenously into humans, and the excreta were collected and analyzed for uranium content. Results from small-animal experiments indicated that bone and kidney are favored uranium deposition sites and excretion is mainly via urine. Tables and figures are included.
