CHEMICAL DOSIMETRY OF PROMPT AND RESIDUAL RADIATIONS FROM NUCLEAR DETONATIONS,
Abstract
Chemical dosimetry studies were made to estimate human exposures to prompt and residual radiations from nuclear detonations. They included measurements of: (1) gamma radiation from fallout at on-site and off-site areas; (2) air-dose and depth-dose distribution determinations in human phantoms placed at positions calculated to receive prompt neutron and gamma radiation exposures in the dose range of medical interest (0 to 1000 rads); and (3) estimates of gamma and mixed neutron plus gamma radiation exposures which might aid the evaluation of Japanese who survived prompt-gamma exposures at Nagasaki as compared with neutron plus gamma exposures at Hiroshima. The feasibility of using direct-reading chemical dosimeters for estimating gamma-ray exposures from nuclear fallout and from prompt bomb gamma radiations was demonstrated. In addition, the responses of single-phase dosimeters to gamma rays plus neutrons provided a useful index of the total exposure because they registered the gamma component accurately and also reflected the amount of associated slow- and fast-neutron radiations with sufficient accuracy (low by 10 to 25 per cent) to aid in the medical evaluation and initial segregation of radiation casualties.
