摘　　要：利用MC法对高频超导电子直线加速器装置感生放射性进行模拟评估。模拟结果表明,结构靶件中部分活化核素活度浓度高于豁免值,低于低水平放射性废物上限值;室内空气中各活化核素活度浓度远低于对应的导出空气浓度;设备冷却水中各活化核素总活度浓度低于排放限值;混凝土中各活化核素活度浓度远低于豁免值。结构靶件中活化核素对室内感生辐射场贡献最大,其他介质中活化核素对感生辐射场的贡献可忽略。The MC method was used to simulate and evaluate the induced radioactivity of the high-frequency superconducting electron linear accelerator device.The simulation results show that the activity concentration of some activated nuclides in the structural target is higher than the exemption value and lower than the upper limit value of low-level radioactive waste.The activity concentration of each activated nuclide in the indoor air was much lower than the corresponding outlet air concentration.The total activity concentration of each activated nuclide in the cooling water of the equipment was lower than the emission limit.The concentration of activated nuclide activity in concrete is much lower than the exempt value.The activated nuclides in the structural targets contributed the most to the indoor induced radiation field,while the contribution of activated nuclides in other media to the induced radiation field was negligible.
