Schemes are given for recording the electromagnetic radiation emitted over a wide radio-frequency range (0.15-30 MHz) by dielectrics when heated with no voltage applied to the specimen and in a constant electric field. As examples, the paper describes the results of studies of pulsed electromagnetic radiation during the heating of specimens of periclase and technical glass, without any voltage being applied to the specimen and in a constant electric field, from liquid-nitrogen temperatures to 1000°C. An amplitude-frequency analysis is made of the radio pulses.
