Abstract

Dosimeter data from the low altitude, high inclination satellite, APEX, flying from 1994-1996 are used to create low altitude dose models for four aluminum shielding thicknesses. These models are appropriately applied to solar minimum conditions. One model is made using the entire data set. The data are also ordered by magnetic activity from which five models are made to show variations in the outer zone electron contribution to dose. The models are imported into a computer utility called APEXRAD such that dose for user-selected orbits and run times may be calculated. The variation of dose with satellite inclination, altitude, solar cycle and magnetic activity is examined using APEXRAD
