在煤田放射性测井工作中,由于不能正确使用必要的射线防护方法,伽玛射线的照射使操作人员身体受到伤害。本文提出了几种基本的射线防护方法,并着重指出了几种屏蔽防护和距离防护的重要作用。文章列出了煤田测井常用屏蔽物质的吸收特性和各种放射性操作与人体接受的辐射剂量,分析了接受剂量与允许剂量的关系,并用数据表明忽视屏蔽防护可能造成的危害,以引起放射性测井工作人员的重视。
In the coalfield radiological logging, the operator’s body is harmed by the radiation of gamma rays because the necessary radiation protection methods can not be used properly. This paper presents several basic methods of ray protection, and highlights several important aspects of shielding and distance protection. The article lists the absorption properties of shielding materials commonly used in coalfield logging and the radiation dose accepted by the human body by various radioactive operations. The relationship between the accepted dose and the allowable dose is analyzed and the data are used to show that the potential hazards caused by the shielding can be neglected to cause the radioactive measurement Well staff attention.
