防护标准工业 X、γ射线探伤防护标准的核心是剂量控制限的标准,即研究制定合适的人体受照剂量限值,以及实施控制的原则。一、国际放射防护委员会的新建议:ICRP 第26号出版物,对放射防护基本标准进行了较大修改。1.把电离辐射引起的生物效应区分为随机效应和非随机效应两类。随机效应是以效应发生的几率作为随剂量变化的指标,即效应的发生率取决于剂量,而严重程度与剂量无关。在放射防护所涉及的剂量范围内,遗传效应和驱体效应中的致癌效应等属于随机效应。非随机效应是指严重程度随剂量而变化的效应.
Protection standards Industrial X, γ-ray detection protection standards at the core of the dose control limit standards, that is, to develop appropriate human exposure dose limits, and the implementation of control principles. I. New Recommendation of the International Commission on Radiological Protection: ICRP No. 26, Major Changes in Basic Radiation Protection Standards. 1. The biological effects caused by ionizing radiation are divided into two categories: random effects and non-random effects. Random effects are based on the probability of an effect occurring as a function of dose, ie, the incidence of the effect depends on the dose, but the severity is not related to the dose. In the range of doses involved in radioprotection, the carcinogenic effects in the genetic and bodily effects are random effects. Non-random effects refer to the effect of severity on the dose.
