Reviews of Geophysics, 1982
This paper reviews the status of radiation belt science at the close of the data acquisition phase (1976–1979) of the International Magnetospheric Study. The purpose is to place recent discoveries in context with respect to long‐standing problems and to indicate possible directions for future research in radiation belt physics.

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

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.

Abstract : This report suggests that electrons trapped in a dipolar field can reproduce some of the observed distributions of emission from extended extragalactic radio sources if the electron pitch-angle distributions are sufficiently anisotropic.

Physics Today, 1966
EIGHT YEARS of space experimentation have elapsed since James A. Van Allen, George H. Ludwig, Carl E. McIlwain and E. C. Ray discovered the earth's radiation belts with a Geiger counter on the Explorer 1 satellite. Almost every flight since has offered the opportunity of finding a different particle, a new energy distribution or an unusual space or ...
