The report summarizes the results of a study of 1975 occupational exposures to ionizing radiation in the United States. Exposure data for all workers exposed to radiation are unavailable, so many of the results are estimates based on extrapolation of partial data that may not be representative of some groups of workers. The primary findings are: (1) About 1.1 million United States workers were exposed to ionizing radiation in 1975. About 370,000 received measurable occupational doses; (2) The collective dose to the work force was nearly 130,000 person-rems. The approximately 5.5% of the work force that received more than 500 mrem accounted for about 75% of this collective dose; (3) The average annual dose to all workers was 120 mrem; for workers with measurable doses, it was 350 mrem; and for workers receiving more than 500 mrem, it was 1,600 mrem; and (4) About 67% of the work force received less-than-measurable doses; about 95% received doses of 500 mrem or less; and about 0.15% received doses exceeding 5 rem. Many other findings and observations are included.
