用蒙特卡罗输运程序FLUKA计算了初级银河宇宙线与大气核相互作用产生的次级粒子谱。在太阳活动极小期和太阳活动极大期，对垂直地磁截止值的几个值进行了模拟。利用适当的转换系数，得到了有效剂量率和环境剂量当量率随地磁截止值和高度的变化关系。对计算结果进行了讨论，并与实验数据和其它计算结果进行了比较。提出了一种计算飞机高度辐射照射量的简单方法。
The spectra of secondary particles resulting from interactions of primary galactic cosmic rays with the nuclei in the atmosphere have been calculated using the Monte Carlo transport code FLUKA. The simulations have been carried out at solar minimum and solar maximum activity, for several values of the vertical geomagnetic cut-off. The effective dose rate and the ambient dose equivalent rate as a function of geomagnetic cut-off and altitude have been obtained using appropriate sets of conversion coefficients. The calculated results are discussed and compared with experimental data and other calculations. A simple method is proposed to calculate the radiation exposure at aircraft altitudes.
