Description/Abstract:
The activities for the Health Physics Group in the Y-12 Plant during December 1947 were mostly centered around the start-up of the New Machine Shop in Building 9766. The Hand Counter was moved to this location to check on hand contamination in the machining of uranium. The hand counts were comparatively low but still higher than current tolerance levels allowed, and efforts were being made to establish adequate handling and glove techniques. Twenty-two air samples were taken at breathing levels, and only one showed a uranium concentration seriously approaching the chemical toxicity tolerance. Four air samples were taken in various locations of Building 9206, and three of those samples showed uranium concentrations far in excess of the accepted tolerance levels. Medical has been requested to make some tests to accurately establish the efficiency of the respirators used. Out of 13 samples of potable water taken in various buildings and sent to the Industrial Hygiene Section at K-25 for analysis, results of 9 of those received to date showed no uranium contamination. Twenty-six charge bottles sent to the shop to be cut into halves were checked for activity level, and twelve were found to be highly contaminated. It was recommended that the bottles be sent to the shop in Building 9204-3 where this work is normally done, and steps were being taken to control the handling of these bottles appropriately in the future.
