This correspondence contains a summary of the data obtained during the month of September 1959 from the Health Physics surveys and monitoring programs for Maintenance Division personnel. The Maintenance Division personnel assigned to the urinalysis program submitted a total of 557 samples to be analyzed for uranium content; 51 of these samples indicated internal exposure greater than the Maximum Permissible Limit (MPL) of 43 mrem/day. Those Y-12 employees who are exposed to radioactive materials while working in ORNL facilities are requested to submit bio-assay samples periodically for analysis by the ORNL Health Physics Bio-Assay Laboratory. Concerning direct radiation, Department 2158 and 2077 personnel wore a total of 22 badges during the month of September 1959. There were no exposures in excess of the control criteria of 2,500 mrem skin dose or 1,250 mrem penetrating radiation dose per quarter or one-third of these figures per month. To determine the levels of air-borne contamination in the B-1 Wing maintenance shop, a total of 51 air samples were taken. None of the samples obtained exceeded the MPL. During the month of September 1959, a total of 133 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 are included with the report.
