透射式CT与自射线式CT检测核废物桶蒙特卡罗模拟

Coupled Transmission CT and Emission CT Monte Carlo Simulation Assay for Radioactive Waste Drum

摘要: 用蒙特卡罗方法对透射式CT(TCT)和自射线式CT(ECT)检测核废物进行模拟实验, 用TCT的模拟结果对ECT的模拟结果进行材料吸收系数校正, 可以较为准确地确定核废物桶中放射性活度的绝对分布, 并可确定放射性核素的种类

Abstract: Using Monte Carlo method the coupled TCT and ECT is simulated to nondestructively determine radioactivity distribution in waste drum. The results of ECT is corrected by using the results of TCT to provide an accurate quantitative absolute measurement of the internal radioacti vity, and radionuclide can be identified by ECT.
