Description/Abstract:
This correspondence is concerning the June 1959 Health Physics Report for the Maintenance Division personnel. During the month of June, the Maintenance Division personnel assigned to the urinalysis program submitted a total of 640 samples to be analyzed for uranium content; 64 of these samples indicated internal exposure greater than the Maximum Permissible Limit (MPL) of 43 mrem/day. During June 1959, there were 2 cases which required personnel be removed from further exposure to uranium and 24 persons whose 13-week cumulative was in excess of 3,900 mrem, the quarterly MPL. Mechanical Division personnel wore a total of 21 badges during this report period. The average radiation exposure indicated by the film badges was 304 mrem for the quarter ending June 1959. No individual's exposure exceeded 2,500 mrem, the permissible average exposure limit for the quarter. From records received since the last report period, Y-12 personnel working in ORNL areas wore a total of 485 film badges. None of the badges indicated exposure of any significance. A total of 33 air samples were taken to determine the levels of air-borne contamination in the B-1 Wing maintenance shop. Six of the samples obtained exceeded the MPL of 70 d/m/M3. During the month of June 1959, a total of 247 smears were taken in Area 5 maintenance shops to estimate the level of removable uranium contamination on surfaces. The average contamination level in the B-1 Wing maintenance shop was in excess of the control criterion of 500 d/m/100cm2. Tables and figures with results are included in this report.
