This paper presents estimates of ionizing radiations in the Earth's atmosphere obtained by calculating primary cosmic ration passing through it. The contribution of protons with energies of up to 200 MeV and neutrons with energies of 0.1 to 100 MeV to the equivalent dose rate produced by fluxes of ionizing radiations of cosmic origin amounts to 90%. The contribution of electrons and gamma-rays is one order of magnitude smaller and the contribution of muons and pions is negligibly small. The paper gives data about the altitude and latitude distribution of equivalent dose rates generated by fluxes of galactic and solar cosmic rays. The dose rate level reaches its maximum at altitudes of about 20 km and in the regions situated to the North of 67 degrees N. 1.
本文介绍了通过计算穿过地球大气层的初级宇宙射线获得的地球大气中电离辐射的估计值。能量高达200兆电子伏的质子和能量为0.1至100兆电子伏的中子对宇宙起源的电离辐射通量产生的当量剂量率的贡献高达90%。电子和伽马射线的贡献小一个数量级，而μ子和π介子的贡献可忽略不计。本文给出了银河宇宙射线和太阳宇宙射线通量产生的当量剂量率的海拔和纬度分布数据。剂量率水平在约20公里的高度以及北纬67度以北的地区达到最大值。 1.
