摘　　要：为了对锂铅合金离线产氚实验方案及人员安全操作规程的制定提供基础数据,保证辐照实验与释氚实验的绝对安全,对锂铅合金样品的活化水平及其杂质的控制要求从辐照剂量率的角度进行了计算和初步分析。结果表明:锂铅合金样品在1013N/(cm2.s)的中子注量率下辐照15 h,经过约10个月的冷却与搁置,剂量率降低到放化实验室操作的剂量率水平要求,且杂质的控制要求较低;但搁置100个月后,仍无法满足普通化学实验室的操作要求。The activation level and impurity control index were calculated and analyzed initially based on irradiation dose rate.And the aim is to provide basic data for out-pile tritium release experiment from lithium-lead alloy and for the establishment of the personnel safety operation rule and regulation to ensure the absolute safety of irradiation experiments and tritium release experiments.The results show that the dose rate of Li-Pb alloy is reduced up to the dose rate level requirement of radiochemical laboratory operation,and the impurity control level is low under 15-hours irradiation at the neutron dose rate of 1013N/（cm2·s） and 10-months cooling and storage.However,the general chemical laboratory operation requirement cannot be met even by 100-months storage.
