The atmospheric cosmic-ray environment is composed of secondary particles produced when primary cosmic rays interact with the nucleus of atmospheric atoms. Modeling of atmospheric radiations is essential for investigating their impacts on human activities such as radiation risks in aviation or scientific fields such as cosmogenic dating. The nuclear transport codes are a common and accurate way to model the cosmic ray interaction in the atmosphere with minimal approximations. However, tracking all produced secondary particles in each event in the whole depth of the atmosphere and sampling many events to obtain the statistically meaningful results would be a computational challenge and disadvantageous from the point of view of time consumption. This paper presents a computational platform names ATMOS CORE based on pre-calculated databases coupled to physical models and computational methods. The fields of application concern the atmospheric cosmic-rays characterization as well as their effects on electronics systems, on the ambient dose for aircrews or the cosmogenic nuclide production for dating activities. Some comparisons between simulations and measurements are also presented and discussed.

基于预先计算的数据库,物理模型和计算方法模拟大气宇宙射线及其影响

大气宇宙射线环境由初级宇宙射线与大气原子核相互作用时产生的次级粒子组成。大气辐射建模对于调查其对人类活动的影响至关重要,例如航空或科学领域的辐射风险,例如宇宙成因测年。核运输代码是一种以最小的近似值模拟大气中宇宙射线相互作用的常用且准确的方法。但是,在整个事件的整个深度中跟踪每个事件中所有产生的次级粒子并采样许多事件以获得统计上有意义的结果,这在计算上是一项挑战,从时间消耗的角度来看是不利的。本文基于结合物理模型和计算方法的预计算数据库,提出了一个计算平台名称ATMOS CORE。应用领域涉及大气宇宙射线的特征及其对电子系统的影响,机组人员的环境剂量或约会活动所产生的宇宙生成核素。还介绍和讨论了仿真和测量之间的一些比较。
