Electron radiation belts can change dramatically in a few seconds or slowly over years. Important issues in understanding such changes are: (1) What is the source of electrons in the radiation belts? (2) How important is radial diffusion compared to other radial transport mechanisms?

The radiation belts of Jupiter
Icarus, 1974The cloud of relativistic electrons which forms the Jupiter radiation belts at a distance of a few Jovian radii from the planet is considered. The inner belt is shown to consist of electrons with about three times the energy of those in the outer zone, and to have an equatorial density which is about one half the peak density in the outer zone.

Abstract The Earth's radiation belts, formed by energetic electrons and ions (principally protons) trapped in the Earth's quasi-dipolar field, are reviewed. The magnitudes of particle energies and fluxes encountered make this a very severe environment in which to conduct space missions.

Tightening the radiation belts [PDF]
Nature Physics, 2005 Extreme solar conditions caused the Earth’s radiation belts to shrink temporarily, yielding an opportunity to investigate particle acceleration in those regions.

The effects induced by the space environment on space vehicles and astronauts no longer need to be demonstrated. The nature of this environment varies greatly between low orbits and higher orbits such as the geostationary orbit and beyond. In this chapter, we attempt to describe the space environment relative to ionizing particles.

, 2015 Abstract : The Earths inner and outer radiation belts, comprising energetic electrons and protons, pose a hazard to DoD spacecraft. Air ForceResearch Laboratory (AFRL) has an ongoing research effort to model and forecast the configurations of the belts, and to develop protective technologies for spacecraft.

Based on the statistical data measured by Van Allen Probes from 2012 to 2016, we analyzed the effects of solar wind plasma flow and interplanetary magnetic field (IMF) on the spatial distribution of Earth's radiation belt electrons (>100 keV).

Jupiter is a copious source of radiowaves having a wavelength of 3–75 cm. The radiation is 20% or so linearly polarized perpendicular to the planet rotation axis, does not vary much in intensity over the entire range of observed frequencies, and changes slowly in intensity over a time interval of the order of a few years.
