Radiation dosage in flight through the Van Allen belt.
A B O U T ten years ago, when avialion medicine developed a seri,ous interest in the problem of cosmic ray ,hazards in flight at the top of and outside the atmosphere, it became common practice to express cosmic ray intensities in terms of tissue ionization dosages, that is, in roentgens equivalent physical ( rep) . This expedited ~he interpretation of the ~;lata of the physicists inasmuch as e...
متن کاملWave-driven butterfly distribution of Van Allen belt relativistic electrons
Van Allen radiation belts consist of relativistic electrons trapped by Earth's magnetic field. Trapped electrons often drift azimuthally around Earth and display a butterfly pitch angle distribution of a minimum at 90° further out than geostationary orbit. This is usually attributed to drift shell splitting resulting from day-night asymmetry in Earth's magnetic field. However, direct observatio...
متن کاملMapping Jupiter's outer radiation belt
Flux maps of energetic ions in Jupiter's outer radiation belt, calculated with the aid of a model of the current sheet magnetic field, are consistent with a spatial distribution that is uniform along field lines and monotonically decreasing with radial distance. This result is supported by numerical ion trajectory calculations that predict uniform filling of drift shells at high L values. Adiab...
