Recent work has suggested very strongly that most non-thermal radio sources emit by the synchrotron mechanism—the radiation of relativistic electrons and positrons in magnetic fields. In this paper a summary of calculations of the total energy in particles and magnetic field in a number of radio sources has been given. Magnetic fields estimated in this way for the Crab, Cassiopeia A, our Galaxy, M 87, NGC 5128, NGC 1316 and Cygnus A are tabulated.
