SHIELDING REQUIREMENTS FOR RADIATION BELT PARTICLES,
Abstract
The proton energy spectrum in the heart of the inner radiation belt is presented, based on experimental data. The degraded spectra resulting from the attenuation of the incident protons by 5, 10 and 20 gm/sq cm of polyethylene are calculated. The air dose rate due to the degraded protons is given as a function of polyethylene shielding thickness. Air dose rates range from 54 r/hr for no shielding to 2 r/hr for 20 gm/sq cm shielding. The bremsstrahlung due to inner-belt electrons is estimated. The dose rate contribution due to bremsstrahlung is considerably less than that due to protons. (Author)
