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 McIlwains 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.
