大多数辐射测量是在沿着轨道飞行的航天器上进行的，轨道倾角高达51.6度。由于在倾角较大的轨道上进行载人飞行任务的前景，最好在高倾角轨道上进行初步的详细剂量测量;由于其极地轨道，罗蒙诺索夫卫星为这种研究提供了良好的机会。我们选择了一种基于半导体探测器的宇宙辐射剂量测量方法。这种方法广泛用于航天器上，包括国际空间站（ISS）上的全时辐射监测。应该指出的是，不仅带电粒子对剂量当量的贡献很大，中子也是如此。半导体探测器对中子辐射的灵敏度低，不足以探测预期的中子通量。在此基础上增加了一个热中子计数器，为估算中子通量沿着轨道的变化提供了一个机会，从而确定了DEPRON（电子、质子和中子剂量计）的设计方案。DEPRON用于登记高能电子、质子和空间辐射核的吸收剂量和线性能量转移谱，以及登记热中子。本文件简要介绍了DEPRON仪器。文中还介绍了它的定标结果和第一次使命的背景辐射测量结果。
Most of the radiation measurements have been made onboard spacecraft flying along orbits with an inclination of up to 51.6 degrees. Due to the prospect of manned missions at orbits with larger inclinations, it is advisable to conduct preliminary detailed dosimetry measurements at a high-inclination orbit; due to its polar orbit, the Lomonosov satellite provides good opportunities for such study. We chose a method of cosmic radiation dosimetry based on semiconductor detectors. This method is widely used onboard spacecraft, including full-time radiation monitoring onboard the International Space Station (ISS). It should be noted that not only did the charged particles contribute significantly in the dose equivalent, but also did the neutrons. Semiconductor detectors have low sensitivity to neutron radiation and are not sufficient for detecting the expected flux of neutrons. We add a thermal neutron counter to the proposed device in order to provide an opportunity for estimation of neutron flux variations along the satellite trajectory.Thus, the design of the instrument DEPRON (Dosimeter of Electrons, PROtons and Neutrons) was determined. DEPRON is intended for registration of the absorbed doses and linear energy transfer spectra for high-energy electrons, protons and nuclei of space radiation, as well as registration of thermal neutrons. The present paper provides a brief description of the DEPRON instrument. Its calibration results and the first mission results of background radiation measurements are also presented.
