WebThe radiation belts are primarily ions and electrons with relativistic energies ( 500 keV). The radiation belts and ring current occupy about the same region in the inner magnetosphere. Both their intensities vary significantly during magnetic storms (i.e., Hamilton et al., 1988; Reeves et al., 2003; Yuan and Zong, 2012; Yuan et al., 2015 ).
A Van Allen radiation belt is a zone of energetic charged particles, most of which originate from the solar wind, that are captured by and held around a planet by that planet's magnetosphere. Earth has two such belts, and sometimes others may be temporarily created. The belts are named after James Van Allen, … Ver más Kristian Birkeland, Carl Størmer, Nicholas Christofilos, and Enrico Medi had investigated the possibility of trapped charged particles before the Space Age. Explorer 1 and Explorer 3 confirmed the existence of the belt … Ver más The inner Van Allen Belt extends typically from an altitude of 0.2 to 2 Earth radii (L values of 1.2 to 3) or 1,000 km (620 mi) to 12,000 km (7,500 … Ver más In the belts, at a given point, the flux of particles of a given energy decreases sharply with energy.
