Charged particle linear energy transfer (LET) distributions of the inner radiation field within an interplanetary spacecraft caused by Galactic Cosmic Radiation (GCR) are a good criterion of adequacy for accelerator-based GCR simulation. This paper presents the results of calculating the LET spectra inside the habitable module of the spacecraft (15 ​g/cm² of Al shell) at the minimum and maximum of solar activity and comparing the calculations with the data obtained by the RAD dosimeter on the flight path to Mars in 2012. It is shown that the shape of the LET spectra weakly depends on the variation of solar activity over a wide range.

生物组织类似物中空间辐射的线性能量转移计算

由银河宇宙辐射（GCR）引起的行星际航天器内部辐射场的带电粒子线性能量转移（LET）分布，是基于加速器的GCR模拟充分性的良好标准。本文介绍了在最小和最大太阳活动下计算航天器可居住舱内（铝壳15 g / cm ²）的LET光谱的结果，并将计算结果与RAD剂量计在太阳活动中获得的数据进行了比较。在2012年到达火星的飞行路径。研究表明，LET光谱的形状在很弱的范围内取决于太阳活动在大范围内的变化。
