Book Description
A simple calculation is done to determine the effects of an orbiting nuclear reactor on the trapped radiation belts. A SNAP-50 reactor, in an equatorial orbit at 1000 km and operating at 8 megw/thrm for a period of one year, is considered as a source of low energy electrons and protons. Neutrons escaping from the reactor decay into electrons and protons and these can become trapped in the earth's magnetic field. Hence, they contribute to the natural fluxes in the radiation belts. Three different source problems are considered: 1.) those neutrons which decay within one kilometer of the reactor; 2.) those neutrons which decay within the entire inner radiation belt; 3.) those neutrons which decay within the entire outer radiation belt. In each region the average equilibrium of reactor-produced electron and proton fluxes at the equator are calculated after reactor operation for one year. These fluxes are compared to the average natural electron and proton fluxes in the regions, and the reactor-produced fluxes are found to be less than 0.1 percent of the natural fluxes in all three cases. All assumptions and calculations are presented in sufficient detail to allow updating with more recent or more exact information. (Author).

Book Description
Space systems planners--space engineers as well as physicists--require for their work accurate values of the fluxes and energy spectra of protons and electrons trapped in the geomagnetic field. Numerous measurements have been made of the Van Allen belt radiations on many satellites, with different instruments and at different times. Most of the experimenters organize their data in terms of McIlwain's B, L coordinates, but intercomparison of the results from different experiments is still complicated by temporal variations of the fluxes and differences in energy response of the various instruments used to obtain the data. A need existed, therefore, for collating the individual measurements and for constructing a model environment. This report contains a description of the model which has been developed for the inner radiation belt. The graphs in this report give a picture of the radiations; card decks containing the actual flux values have also been prepared and can be used in subroutines of larger computer programs. In addition, codes have been developed for integrating the flux along satellite orbits.
