Current research seeks to explore the effects of space radiation on humans on Earth as well as in the spacecraft systems and instruments, which are significant considerations for life on Earth and space missions respectively. Exposure of radiation to humans on Earth is a ubiquitous concern while astronaut exposure is a serious concern for manned missions. In order to meet these challenges, the radiation levels of the specific environment must be understood and accurately modeled with respect to lower levels of radiation experienced daily on Earth. The nature of the environment differs greatly between changes in altitude in accordance to low Earth orbits and higher Earth orbits. The variations coincide with the phase of the solar cycle, thus, leading to a question of non-ionizing (low energy) or ionizing (high energy) radiation. In this research, the author concentrates mainly on charged particle radiations in the near-Earth region based on previous research, to link between radiation both on Earth and outer space missions. Explanations of the radiation belts and particles of solar and cosmic origin are considered. This paper not only analyzes the effects of radiation, but also presents a summary of the traditional models accompanied by their implication areas and restrictions that are followed by discussion of some recent model developments and measures for protection.
