Description/Abstract:
This document concerns a metallurgical report for the month ending August 31, 1944, for the Health Physics Section of the Health Division and Biological Section of the Research Division at Clinton Laboratories. A scum consisting of algae and radioactive deposits is creating a problem in connection with waste disposal in the new settling pond. About 15 percent of the high pocket meter readings can be identified with radiation exposure. Rough handling and loose caps probably account for most of the high readings. The English-Mast hand counter is meeting a need in the product laboratories. Atmospheric radiation was found to be directly correlated with the activity of the pile. Radioactive scum formed by algae is collecting on the surface of the settling pond and is found in various parts of White Oak Creek system. Mud samples indicated a progressive increase in the activity of the drainage system at varying points during the past two months. Mice have been exposed to graded doses of slow neutrons, and preliminary results indicated that the median lethal dose is of the order of an 8-hour exposure to a slow neutron flux of 6 x 10(8)n/cm2/sec. It now looks possible to eliminate entirely the necessity of "hot" chemistry in fission product preparations, with its attendant exposure hazard, and rely entirely on adsorption columns. During the month, the Chemistry Division has completed the all-glass remote controlled dissolver, and we have completed the final tests on both stages of the remote controlled eiher-extraction apparatus. It has been found that following an exposure to air-borne fission products for periods up to 31 days, about 20 percent of the original material is fixed in the bones, but the specific activity is still higher in the lungs than in the bones. Tables are included.
