A theory of the radiation belt
Planetary and Space Science, 1965Abstract A theoretical investigation of the properties of a plasma in the vicinity of a magnetic dipole is made, and the conditions for stability of the plasma derived and applied to the Earth's radiation belt. During solar flares oscillations may be set up in the plasma, and the frequency of such oscillation is calculated.

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.

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

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.

Nature, 1979
Several decades of observations have failed to resolve the problem of the interpretation of extended extragalactic radio sources1,2. Most current models invoke the ejection of pairs of plasmoids or relativistic electron beams from the parent elliptical galaxy by various mechanisms3–5. As these theories generally predict the relative orientations of the

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.

For the low altitude region near the Earth (250-1000 km), where the human activity, both commercial as well as scientific, has greatly increased over the last decades, it is particularly important to accurately model the radiation environment. As we briefly noted in Chapter 1, measurements carried out since the 1950s have shown the existence of ...

Space Science Reviews, 1979
The recent close encounters of Pioneer-10 (December 1973) and Pioneer-11 (December 1974) with the planet Jupiter provided the first in situ observations of zenomagnetically trapped particle radiation. Such observations represented a major advance in planetary research.
