Abstract
The evaluation of the hazard posed to the skin by very small radioactive sources (diameter 2 at a depth of about 100-150 µm which would prevent the occurrence of even superficial transient ulceration. The NCRP have used primarily US pig skin data and have produced a criterion which is aimed to prevent the occurrence of a more severe response of acute deep ulceration. The NCRP suggested exposure limit, which is given in terms of a total beta particle exposure of 1010, is less restrictive than that suggested by the ICRP task group by a factor of about 5. The disparity reflects the different levels of acceptable damage and possibly some differences in dose estimates used in the animal studies on which the threshold criteria are based. Both criteria are significantly less restrictive than the hot particle exposure limits previously employed.This publication has 0 references indexed in Scilit:
