一、最近几年出现的新型射气测量仪器最近几年来射气测量仪器有了新的发展,在长期使用的CΓ-11、CΓ-1M和CΓ-2M几种静电计仪器之后,又出现了数种新型射气测量仪器。根据苏联已公布的资料来看,新型射气测量仪器的结构大致有两种:1)仍然是电离室加静电针;2)闪烁室加脉冲计数电路。前一种为早期的CΓ-11、CΓ-1M和CΓ-2M等型仪器所采用的结构,后一种为新型结构;前者测量电离电流,后者可测量气体或粉末试样的α闪烁脉冲。
New Radiation Measuring Instruments Emerging in Recent Years Radiometric instruments have undergone a new development in recent years. After long-term use of several electrometer devices such as CΓ-11, CΓ-1M and CΓ-2M, Several new gas measurement instruments. According to the information published by the Soviet Union, the structure of the new radiometric measurement apparatus is roughly divided into two types: 1) the ionization chamber plus an electrostatic needle; and 2) a flashing chamber plus a pulse counting circuit. The former is a structure used in earlier CΓ-11, CΓ-1M, and CΓ-2M instruments. The latter is a new structure; the former measures ionization current, which measures α-scintillation pulses of gas or powder samples .
