A total of 88,283 DOE and DOE contractor employees were monitored for whole-body ionizing radiation exposures in 1983. This represents 56.6% of all DOE and DOE contractor employees and is an increase from the number of individuals monitored in 1982. In addition to the employees, 84,851 visitors were monitored. Of all employees monitored, 56.5% received a dose equivalent that was less than measurable, 41.6% a measurable exposure less than 1 rem, and 1.9% an exposure greater than 1 rem. The exposure received by 94.6% of the visitors to DOE facilities was less than measurable. Only 5.4% of the visitors received a measurable exposure less than 1 rem, and <0.01% of the visitors received an exposure greater than 1 rem. No employees or visitors received a dose equivalent greater than 5 rem. The collective dose equivalent for DOE and DOE contractor employees was 7858 person-rem. The collective dose equivalent for visitors was 300 person-rem. The average dose equivalent for all individuals monitored was 47 mrem and the average dose equivalent for all individuals who received a measurable exposure was 190 mrem. The highest average dose equivalent for all monitored employees was observed at fuel fabrication facilities (235 mrem) and the lowest among visitors (4 mrem) to DOE facilities. These averages are significantly less than the DOE 5-rem/y radiation protection standard for whole-body exposures. Five cases of internal depositions were reported in 1983. In all cases, the depositions were less than the annual dose-equivalent standard. Internal depositions were the result of accidental, not planned, exposures. A total of 7449 monitored employees terminated their employment in 1983. The average cumulative dose equivalent for terminated employees who worked one to two years was 0.33 rem; two to four years, 0.30 rem; four to six years, 0.41 rem; and longer than six years, 3.70 rem. 5 figs., 10 tabs.
