Description/Abstract:
This document contains the Health Physics Division Annual Progress Report for the period ending July 31, 1957. A device to measure directly the body burden of enriched uranium in a small live animal was designed and constructed. The Garwood procedure for fitting nonlinear curves was applied to linear combinations of exponentials. It was shown uranium concentrates in the proximal convoluted tubules of the kidney, and for this reason is considered to be the critical organ for uranium toxicity. The uranium-fume inhalator has undergone quantitative tests. An analytical procedure was developed for the determination of uranium alpha activity in urine. White Oak Lake was drained in October 1955; soil and plant samples were taken of the lake bed and analyzed for Sr-90 and Cs-137. A program of field studies on arthropods was initiated, with the basic aspects oriented towards investigations of populations and of the food web, and the applied studies concerned with the passage and dissemination of radionuclides through these components of the ecosystem. Monitoring of the core wells located within and around the margin of the ORNL waste pit area indicated seepage containing Ru-106 and free nitrates had migrated from the pits through the Conasauga shale directly and by means of ground fissures for some distance. Biological surveys of the Clinch River above White Wing Bridge showed almost no suspended organisms. Laboratory work was completed for the experiment to determine the biophysical factors used in the calculation of the MPC values 42,43 for Sr-90 + Y-90. About 50,000 spectrographic determinations were made during the past year on human tissues, and significant differences in trace element distribution were found in African natives. It was also planned to extend or develop analytical procedures by flame photometry for other specific elements as a check on the spectrographic determinations of these elements. The feasibility of determining the critical fission products in soil subjected to high temperatures was studied, and results indicated the tracers are relatively firmly fixed to the soil at 1000 degrees Celsius but not at 110 degrees Celsius. A prototype experiment was designed and equipment was being fabricated to study the disposal of high-level wastes by "adiabatic" self sintering. The study of the problem of disposal of radioactive wastes into deep wells was confined to an attempt to determine the critical factors involved. Laboratory soil column studies of intermediate-level wastes were done; a search for radionuclides other than the major long-lived fission products indicated the presence of cobalt and antimony. The Ichiban Project was started in 1956, and the ultimate objective was to determine the absorbed doses of fast neutrons and gamma radiation received by survivors of the nuclear bombing of Hiroshima and Nagasaki; a Liaison Pool was established to closely coordinate the dosimetry data accumulated through experimentation and calculation with the medical records of the Atomic Bomb Casulty Commission. Figures and tables are included.
