Description/Abstract:
The two week period covered in the report was a period of decontamination of Cell B and of general building and equipment repair in 706-D. No serious overdoses or accidents occurred during this period. The men worked at all times on a basis of 50 mr/day as a tolerance dose (a standard set by building operaitons) which allowed a considerable margin of safety; a great advantage in very "hot" work such as encountered in Cell B. Three operation supervisors received overdoses when they kept running in and out of the cell despite constant warnings from Health Physics; and Health Physics men themselves, who, since the department was understaffed, had to do more "hot" surveys than normal. Cell B instrument readings were taken at Points B12, B6, B3, B9, B11, B7, B8, B19, doorway, and center of cell. B11 and B8 were off scale at greater than 20 r/hour. Presently, general background in the cell is about 250 to 300 mr/hour and no tank remaining exceeds 1.5 r/hour. Methods of the decontamination undertaken are described. Radiation continues to remain above a level where repairs can not easily be made in the cell with adequate time allowance. In general, operations in the building have proceeded without hazard despite the difficult nature of the work.
