摘要
本文介绍KF606B型氡(指222Rn,下同)和γ个人剂量计的结构和性能。剂量计采用固体核径迹探测器CR39和热释光探测器LiF(Mg,Cu,P),无源式累积测量方法。设计中考虑了氡测量开关(即非使用期间关闭氡测量)、防水、防尘等技术措施。在实验室和矿山现场实际应用中对剂量计各项性能进行了测试和验证,结果表明,剂量计具有适应矿山实际环境条件、灵敏度合适、探测下限较低等特点,并且体积小、重量轻、使用简便。目前该剂量计已定型生产,应用于铀矿、煤矿工作人员个人剂量监测和工作场所空气中氡浓度和γ辐射剂量率水平的调查测量,还用于居民室内氡浓度调查等工作中。
A kind of Rn/γ passive personal dosimeter named type KF606B has been developed in BRICEM. The dosimeter adopts CR39 for Rn measurement and TLD（Mg, Cu, P） for γ measurement. Some special designs of the dosimeter have been made including Rn switch （to proof environmental Rn exposure while not in use）, water and dust proof, etc. The dosimeter was tested in laboratory and in underground mines, some advantages are presented of suitable sensitivity, lower detection limit, wide environment applicability, pocket size and easy to use, etc. The dosimeter has widely been applying to personal dose monitoring for Uranium miners, coal miners and radon survey in dwellings in China.
