Radiation protection for industrial radiography in the aerospace industry

An outline account is given of the general radiation protection policy of the Boeing Co.. Eighty radiographers are employed, operating ninety radiation sources, and taking 10,000 radiographic exposures per month. The radiographers average less than 100 milliRem whole body exposure per year. They have never been cited for governmental non-compliance, nor have had any radiation accidents. X-ray units, accelerators, and radioactive materials are used in the company radiographic inspection program on aircraft, missiles, and seacraft. The protection program is discussed under the following headings: hazard analysis, facility and equipment design, program administration, and evaluation of the protection system. (U.K.)
