Концептуальный подход к созданию комплексной системы радиационной защиты в условиях воздействия высокодозных полей ионизирующего излучения

Abstract

The general approaches and criteria for substantiating the complex system of radiation protection (RP) of a human operator in the conditions of work in high-dose fields of ionizing radiation are considered. When planning work in such conditions, it is advisable to consider a set of measures of an organizational, technical and medical nature. Each activity has its measures own limits to reduce the dose load on the human operator or the development of adverse effects of radiation, and in some cases only a combination of them can give a certain protective effect, allowing to carry out the necessary activities in such conditions. If an operator works in mobile technical facilities (for example, a bulldozer, a caterpillar all-terrain vehicle, a helicopter, etc.) an important place is occupied by the issue of strengthening the technical component of the RP, primarily by engineering the design of additional shield elements. The biomedical rationale for the optimality of such protection is givenensuring maximum protection of vital organs, in the first place, red bone marrow, a significant volume of which is concentrated in the bones in the lumbar vertebrae, sacrum and pelvis. Several examples of the performance of professional activity of operator in the conditions of high-dose ionizing radiation fields and an expert evaluation of the limiting capabilities of the technical and medical component of the integrated RP are considered.
