- Аннотация: In a wide range of characteristics of the corpuscular radiation of the nearEarth outer space (SE), protons dominate (more than 90%), which have a highpenetrating power and cause radiation damage and upset the onboard electronics(OBE) of the spacecraft. The nature of failures can be either degradation of theinitial characteristics of OBE elements with increasing radiation dose, or a failure as a result of the generation of a sufficiently high number of electron-holepairs during ionization of OBE atoms by passing primary radiation (protons), orproducts of nuclear reactions between primary radiation and OBE atomic nuclei.In the report we shall give a brief analysis of the probability of failures of electronics under the influence of primary radiation and fragments-products of nuclear reactions, which have a significantly higher ionizing capacity
