卤素管在放射性强度和剂量测量中用途广泛。为了配合对α,β,γ和X等四种射线都灵敏的小型剂量报警仪研制任务,我们开展了四射线卤素管的研制,现在已经研制成功,并且投入批量生产,提供用户使用。四射线卤素管采用钟罩形端窗结构,管身使用氧化镁陶瓷材料;云母作为端窗,其厚度≤2 mg/cm~2;阴极和阳极引线使用特制的高铬钢丝,其直径为φ0.4mm;阳极
Halogen tubes are widely used in radioactive intensity and dose measurement. In order to cooperate with the task of developing a small dose alarm device sensitive to four kinds of rays, such as α, β, γ and X, we developed a four-ray halogen tube that has been successfully developed and put into mass production to provide users with it. The four-ray halogen tube adopts bell-shaped end-window structure, and the tube body is made of magnesia ceramic material. Mica as the end window has a thickness of less than or equal to 2 mg / cm 2. Cathode and anode lead wires are made of special high- .4mm; anode
