We provide a quantitative estimate of the radiation dose during relativistic electron precipitation (REP) events at the International Space Station (ISS). To this goal, we take advantage of the data collected by the CALorimetric Electron Telescope, the Monitor of All‐sky X‐ray Image, and the Space Environment Data Acquisition equipment‐Attached Payload. The three ISS detectors offer complementary REP observations, including energy spectra and flux directional information, during a period of approximately 2.5 years, from November 2015 to March 2018. We have identified 762 REP events during this period from which we obtain the distribution of radiation dose, relevant to extravehicular activities outside the ISS.

国际空间站相对论电子降水过程中的辐射剂量

我们提供了国际空间站(ISS)相对论电子沉淀(REP)事件期间辐射剂量的定量估计。为了实现这一目标,我们利用了量热电子望远镜,全天空X射线图像监视器和空间环境数据采集设备附带的有效载荷收集的数据。从2015年11月到2018年3月,在大约2.5年的时间里,这三个ISS检测器提供了互补的REP观测,包括能谱和通量方向信息。在此期间,我们已经识别出762次REP事件,从中我们可以获得辐射剂量的分布,与国际空间站外的舱外活动有关。
