Space, atmospheric, and terrestrial radiation environments

The progress on developing models of the radiation environment since the 1960s is reviewed with emphasis on models that can be applied to predicting (he performance of microelectronics used in spacecraft and instruments. Space, atmospheric, and ground environments are included. It is shown that models must be adapted continually to account for increased understanding of the dynamics of the radiation environment and the changes in microelectronics technology. The IEEE Nuclear and Space Radiation Effects Conference is a vital forum to report model progress to the radiation effects research community.
