BETA SKIN-DOSE MEASUREMENTS BY SPECIALLY DESIGNED FILM-PACK DOSIMETERS,
Abstract
A film dosimetric method for determining the betaray dose received directly below the cornified epithelial surface of the skin (7 mg/cm squared) from exposure to fall-out fission products was used during Operation Teapot. The design and construction of the special film pack required and the method of reading and interpreting the films are discussed. Nine or ten packs were used for each of the four shots of interest to Project 37.2, March 7 (Turk), March 29 (Apple I), April 15 (Met), and May 5 (Apple II). Each pack was exposed only once. In the case of the first two shots, no fall-out occurred at the pack stations selected. The results obtained from film packs exposed on Met and Apple II indicated that the maximum individual fall-out particle skin dose varied from >3000 rep beta at 7 miles from Ground Zero to 470 rep beta at the 140-mile arc. Tables are included which summarize the exposure conditions and results for all the film packs. (Author)
