我们提供了在国际空间站（ISS）的相对论性电子沉淀（REP）事件的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-附加有效载荷收集的数据。国际空间站的三个探测器在2015年11月至2018年3月的大约2.5年期间提供补充REP观测，包括能谱和通量方向信息。在此期间，我们确定了762个REP事件，从中我们获得了与国际空间站外的舱外活动有关的辐射剂量分布。
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.
