Abstract : The Space Trajectory Radiation Exposure Procedure (STREP) is designed to compute the time-integrated spectra for any specified trajectory in cislunar space for any combination of the several components of space radiations. These components include Van Allen protons and electrons; solarflare protons, electrons, heavy particles, and gamma radiation; cosmic protons and heavy particles; albedo neutrons, and aurora borealis gamma radiation. The program will also calculate the accumulated dose behind a thin vehicle skin at any time after the start of the mission. The technique of interpolation for intermediate points along the prescribed space trajectory is described in detail. The method of representation of the space radiation data as input for the calculation of the dose and time-integrated spectra is discussed. (Author)
