Penetrating rays readily deflected by a magnetic or electric field, emitted by radioactive substances, as radium. They consist of negatively charged particles or electrons, apparently the same in kind as those of the cathode rays, but having much higher velocities (about 35,000 to 180,000 miles per second).
