为使核探测器具有良好的技术性能,对探测器的结构也提出了严格的要求,如避光、防潮、防磁、防振、防辐射以及为适合探测器的使用对结构形式、体积、重量等提出的要求。本文仅讨论对其中的防辐射问题以及辐射装置的结构设计。 许多放射性测量仪器中,防护装置是一个不可缺少的组成部分。其中有的是局部性防护,有的是整体防护。因此,这种防护形式是多种多样的,但其防护的目的不外乎两 In order to make the nuclear detector have good technical performance, the structure of the detector has also put forward strict requirements, such as protection against light, moisture, magnetism, vibration and radiation as well as the use of the detector for the structure, volume, weight And other requirements. This article discusses only one of the radiation protection issues and structural design of the radiators. In many radiometric instruments, guards are an integral part. Some of them are partial protection and some are overall protection. Therefore, this form of protection is varied, but its purpose of protection is no more than two
