The mono graph includes eight chapters, and their contents conceal all important features of the matter: 1. creation and short his tory ofthe radiation challenge and historical past info ofradiation risk within the near-Earth and interplanetary house. 2. basic description of radiation stipulations and major resources of charged partic1es within the Earth's setting and interplanetary area, results of house atmosphere on spacecraft. three. simple information regarding actual stipulations in house and major resources of charged debris within the Earth's atmosphere and interplanetary area, within the context of "Space W eather" tracking and prediction. four. Trapped radiation belts of the Earth (ERB): concept in their starting place, spatial and temporal dynamics, and experimental and statistical versions. five. Galactic cosmic rays (GCR): adaptations of vigorous, temporal and spatial features, long term modulation, and anomalous cosmic ray (ACR) part, modeling oftheir dynamics. 6. construction of full of life debris (SEPs) at/ne ar the sunlight: on hand databases, acceleration, propagation, and prediction of person SEP occasion, statistical versions of sun cosmic rays (SCR). 7. current empirical ideas of estimating, prediction and modeling of radiation threat, methodical ways and constraints, a few questions of alterations within the Earth's radiation surroundings because of alterations of the sunlight task point. eight. Unresolved difficulties of radiation chance prediction and spacecraft defense, radiation experiments on board the spacecraft, estimating of radiation stipulations in the course of interplanetary missions. area doesn't let us clarify whenever the solar-terrestrial and radiation physics nomencIature utilized in present English-language literature.
