“…2.2 Ambient dose equivalent rate of radioactive corrosion products adhered to skin surface The case of an RCP adhered to the surface of a water phantom (whose radiation absorption and scattering properties are similar to those of human tissue) having dimensions of 50 × 50 × 20 cm 3 was considered, and the gamma-rays emitted from the RCP were tracked by the original Monte Carlo method. 3,4) In this code, BERGER et al 5) 's photon cross-section data and HUBBELL et al 6) . 's incoherent scattering functions and form factors were used.…”

Radionuclide contamination is one of the accidents that might occur while carrying out a periodical inspection of nuclear power stations during normal reactor operation. When such an accident occurs, rescue and medical personnel, involved in transporting and treating affected workers run the risk of exposure to secondary radiation. In this study, the ambient dose equivalent rate at a certain distance from the surface of the human body contaminated with typical radioactive corrosion products was calculated. Further, the relationships among the adhesion area, contamination density, and secondary exposure dose were clari ed. The secondary exposure dose and permissible working hours in a radiation emergency medicine were estimated by presenting these relationships in the form of a chart and by specifying the contamination levels.
