⁹⁰Sr-⁹⁰Y源衰变电子在空气介质中的径迹结构理论模拟

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.
