Design and analyse space radiation shielding for a Nanosatellite in low earth orbit (LEO)

In this paper we design and analyze space radiation shielding for Nanosatellite with perigee 250 km and apogee 650 km, with endurance one month in solar max activity. At first step space radiation environment simulated. The proton spectrum energy in inner Van Allen belt varies from 0.01 MeV to 400 MeV. In second step radiation shield designed. The shield was made by AL7075. Analyzes done with formula calculation and MCNP-X.
