摘　　要：采用FLUKA蒙特卡罗程序计算了兰州重粒子加速器所产生感生放射性核素的种类及其活度,研究了其活度随时间的变化关系,使用γ谱仪测定了冷却后加速器腔壁中长寿命放射性核素的γ能谱图,分析了感生放射性对放射性工作人员和公众的影响,提出了相应防护措施的建议。Studying induced radioactivity of Heavy Ion Research Facility in Lanzhou （HIRFL） which is significance for radiation protection. The radionuclides and radioactivity were calculated by using the FLU- KA Monte Carlo code in this paper, the relationship between time and radioactivity was studied, and the γ energy spectrum diagram of the long life radionuclides in the accelerator cavity was measured with the gam- ma ray spectrometer. The effects of radionuclides for workers in radioactive areas and the public were ana- lyzed, and according to the characteristics of these radionuclides the protective measures were proposed.
