A simulation of the radiation field inside a habitable module (a diameter of 6 m and length of 12 m) of a spacecraft generated by isotropic Galactic Cosmic Radiation (GCR) in deep interplanetary space is carried out for minimum and maximum solar activity using the FLUKA code. Protons, alpha-particles, deuterons, $$^{\mathrm {3}}$$ 3 He, and nuclei with $${Z} > 2$$ Z > 2 are considered as primary GCR irradiating the spacecraft isotropically. The following particles are included in FLUKA radiation transport through the module shell ( $$15\hbox { g/cm}^{\mathrm {2}}$$ 15 g/cm 2 of Al): protons, neutrons, $$\gamma $$ γ -rays, electrons, $$\pi ^{\mathrm {\pm }}$$ π ± -mesons, $$\mu ^{\mathrm {\pm }}$$ μ ± -mesons d, t, and nuclei from He to Ni. The inner particle spectra are needed to assess the astronaut’s radiation risk in a long-term interplanetary mission.

星际飞船内部辐射场模拟

使用 FLUKA 对由各向同性银河宇宙辐射 (GCR) 在深星际空间中产生的航天器可居住模块（直径为 6 m，长度为 12 m）内的辐射场进行了最小和最大太阳活动的模拟代码。质子、α 粒子、氘核、$$^{\mathrm {3}}$$ 3 He 和 $${Z} > 2$$ Z > 2 的原子核被认为是各向同性照射航天器的主要 GCR。以下粒子包含在通过模块壳的 FLUKA 辐射传输中（$$15\hbox { g/cm}^{\mathrm {2}}$$ 15 g/cm 2 的铝）：质子、中子、$$\gamma $$ γ -射线，电子，$$\pi ^{\mathrm {\pm }}$$ π ± -介子，$$\mu ^{\mathrm {\pm }}$$ μ ± -介子 d, t ，以及从 He 到 Ni 的原子核。
