兰州重离子研究装置（HIRFL）感生放射性剂量率的测量

Abstract

本文报道兰州重离子研究装置（ＨＩＲＦＬ）实验终端钢筒表面和实验靶处的感生放射性外照射剂量率测量的方法和结果，分析了感生放射性剂量率的衰减规律。根据实测数据评估了操作人员所受的外照射剂量，并提出了为降低操作人员受照剂量而采取的防护措施。The measurement methods and results of the dose rates from induced radioactivi-ties on the surfaces of stainless steel tubes and some experimental targets in HLRFL are pre-sented in this paper.The decay curves of induced radioactivities were analysed.Based on theexperimental data,the doses of operators were estimated,and protection methods were sug-gested in order to decrease doses to operators
