Abstract : The following areas are treated: (1) The radiation spectrum emitted under the simultaneous action of Coulomb forces and an external magnetic field. (2) The radiation emitted by free particles in the neighborhood of the plasma frequency where the collective behavior of the plasma electrons becomes the dominant factor. (3) The radiative transfer problem in dispersive media which relates the observable spectrum of a plasma source to the internal parameters, such as temperature and density. (4) Departures from thermodynamic equilibrium in continuous energy states, when the radiative interactions can be separated from collisional transitions. (5) Relativistic corrections that turned out to be negligible under the conditions envisaged in the preceding paragraphs. (Author)
