一、序言由于原子能事业的迅速发展,使用放射性同位素的工作人员愈来愈多,他们在工作中或多或少的接触到放射线,各种射线无论是体外照射或特别是放射性物质进入人体内部情况下,在强度超过一定量时都会给人体以有害的影响,故在各种放射性同位素的应用工作当中应该充分估计到在某些情况下射线对人们有可能危害的不利的一面(指过量照射),但恐惧是不必要的。所以在使用放射性同位素的数量(强度)可能对人体有危害的地方,必须实施一系列的安全保护措施及防护规则,以保证工作人员的安全。本文拟对射线防护工作作一初步介绍。 I. Preface As a result of the rapid development of atomic energy, there are more and more workers using radioisotopes. They are exposed to more or less radiation during their work. All kinds of radiation, whether in the form of in vitro exposure or radioactive material in particular, enter the human body Under the intensity of more than a certain amount will give the human body harmful effects, so the application of various radioisotopes should be fully estimated in some cases under the rays of the people may harm the negative side (referring to excessive exposure) But fear is unnecessary. Therefore, the use of radioisotopes (intensity) may be hazardous to human health, we must implement a series of safety precautions and protection rules to ensure the safety of staff. This article intends to conduct a preliminary introduction of radiation protection work.
