Geostationary Space: The Radiation Environment and Effects on Electronics Under Various Shielding Configurations

In an earlier paper, we presented space radiation effects data on electronics under certain shielding configurations on spacecraft residing in a geostationary orbit (6.6 RE). In this paper we re-examine the geostationary space radiation environment, which consists of high-energy (<~6 MeV) electrons and low-fluence, low-energy protons. In addition, we also include the galactic cosmic radiation (GCR) and possible solar proton event (SPE) effects. The results of a parametric study of the trapped, GCR, and SPE radiation environments on electronics for a variety of shielding configurations using a variety of shielding materials is discussed in detail.
