Description/Abstract:
This correspondence contains the February Health Physics report for the Maintenance Division Personnel. Personnel working in uranium handling areas are requested to submit urine samples periodically. By analyzing the urine for uranium, an estimate of the internal exposure of these people is obtained. An overall participation effort for the urinalysis program by the division was 93 percent which is considered very satisfactory. Departments 2001, 2014, and 2077 were to be commended for their excellent participation. In view of the fact that the urine analysis results for personnel of the maintenance department seemed to show a rising trend, a study was made of the air and surface contamination in the B-1 maintenance shop of Building 9212. Smear samples were taken on the floor by the standard smear technique. These samples indicated an average contamination level of 2000 d/m/100cm2, which is four times the control criterion of 500 d/m/100cm2 for uranium handling areas. Personnel handling radioactive materials under the X-10 jurisdiction but on the Y-12 payroll are requested by the X-10 Health Physics group to submit samples periodically. From records received since last report, Y-12 personnel working in ORNL areas wore a total of 252 film badges with none showing exposures to penetrating radiation greater than 50 percent of the Maximum Permissible Limit. Graphs with urine averages and general air results are included in this report.
