摘　　要：中子固体气泡探测器被认为是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, 其灵敏度达到每毫雷姆40个气泡. 还介绍了个人中子剂量气泡探测器的原理和制作过程.Neutron solid bubble detector was considered as a unique one for meeting the need of the personal neutron dosimeter recommended by International Committee of Radiation Protection,ICRP60.It has the flat response for neutron from low energy to high energy,and insensitive for gamma rays. In this work,superheated liquid drops were dispersed into a kind of soft polymer homogeneously.A personal neutron bubble dosimeter has been made,and the sensitivity reached to about 40 bubbles/mrem.The principle and the processing procedure of bubble detector were also introduced.
