Theoretical Simulation of Track Structure in Atmosphere Produced by 90Sr-90Y Source

  • 摘要: 利用Monte-Carlo方法模拟了90Sr-90Y源衰变电子径迹及能谱分布,分析比较了源衰变电子与次级电子、轫致辐射光子能量分布和空间径迹结构的差异。模拟结果为90Sr-90Y源的辐射防护、屏蔽设计及其应用研究提供了相关理论参考。

     

    Abstract: The distribution of the decay electron tracks and spectra induced by 90Sr-90Y source were simulated with Monte-Carlo method. The track structures and spectra of decay electrons were compared with those of secondary electrons and bremsstrahlung photons, and the differences among them were analyzed. The simulation results may offer some theoretical references for radiation protection, shielding design and application studies of 90Sr-90Y source.
