摘要： 为了掌握常用个人防护用品对不同能量β射线的防护效果,在⁸⁵Kr和⁹⁰Sr-⁹⁰Y标准β辐射场中,测量给出了各种组合情况下常用个人防护用品对定向剂量当量率公式β射线防护效果较差,对于高能β辐射场所作业人员,给出了开展弱贯穿辐射监测的方法和防护的措施。

Abstract: In order to identify the protection effect of personal protective equipment on different energy β rays, the protection effects of personal protective equipment on H·′(0.07) and H·′(3) under various combinations of different energy β radiation fields were measured in ⁸⁵Kr and ⁹⁰Sr-⁹⁰Y standard β radiation fields. During the outage of the nuclear power plant,the weak penetrating radiation protection effect of personal protective equipment on some positions was measured. The results show that the protective effect of personal protective equipment on field radiation is different because of the different β/γ value of the surface of the equipment being measured. Especially in the places with strong γ rays,the protective effect of personal protective equipment on H·′(0.07) and H·′(3) is generally poor, while the protective effect of protective glasses against weak penetration radiation is rather significant. It is suggested that workers should wear protective glasses in high energy β radiation field to reduce the dose of lens. Due to the poor protective effect of personal protective equipment on high-energy β radiation,the monitoring methods and protective measures for workers working in high-energy β radiation sites are given.

Key words: β ray, attenuation ratio, H·′(0.07), H·′(3)
