摘　　要：固体气泡探测器被认为是目前唯一能够满足国际辐射防护委员会ICRP60要求的个人中子剂量计,它具有从低能中子到高能中子的平坦响应曲线和对γ射线不灵敏的优点。本工作将过热液滴均匀地分布在一种软聚合物中,制成了个人中子气泡剂量计,其灵敏度最高可达到4bubbles/μSv。本文重点介绍了个人中子剂量气泡探测器的原理和制作过程。Neutron solid-state bubble detector is considered as a unique one to meet the needs of the personal neutron dosimeter recommended by International Committee of Radiation Protection, ICRP60, at present. It has the fiat response of neutrons from low energy to high energy, and is insensitive to gamma rays. In this work, superheated liquid drops were dispersed into a soft polymer homogeneously. A personal neutron bubble dosimeter has been made, and the sensitivity reached to about 4 bubbles/μSv. The principle and the processing procedure of the bubble detector were also introduced in this paper.
