The objects of this study were 1 Conduct a comprehensive literature search to determine the state-of-the-art knowledge of the effect of atmospheric radiation components on semiconductor materials from sea level to the top atmospheric layers. Emphasis shall be placed on particle propagation, radiation effects on semiconductor materials, and methods of calculating nuclear reaction cross sections. A comprehensive survey shall be made on the interactions between atmospheric components and cosmic rays and the secondary emissions and energy spectra produced. 2 Generate propagation algorithms to describe the penetration of primary cosmic rays into the atmosphere and the production of secondry emissions. 3 Calculate the energy loss rates in semiconductor materials for various cosmic ray components as a function of altitude, geomagnetic location, and zenith and azimuthal angles.
