Abstract
A statistical study of occupational radiation exposure in New York State industry, based on personnel monitoring records, survey data and results of medical examinations, was made by the Labor Department. Exposures were classified by source, occupation and industry. The results indicated that over 90% of the exposures were below the NCRP recommended dose limit of 100 mrem/week, and that the contribution of occupational exposure to the general population dose was less than 0.3%. The highest external exposures noted were among workers in radium processing, luminous dial painting, industrial radiography and nuclear fuel element fabrication. Sampling results indicated that air-borne concentrations of radioactive contaminants in all but a few installations were below 10% of the MAAC.
