A radio-frequency monitor for protection against overexposure from RF heaters.

Abstract

Extensive investigation on the various potentially polluting RF sources has led to the conclusion that the largest proportion of problems arising from possible RF hazards originates from industrial heating machines (short-wave). In particular, these turn out to require checks due to their intrinsic and induced instabilities. Through the analysis of RF leakage characteristics of these machines, the problem is simplified and the solution is presented in terms of an RF hazard monitor which can be used by non-specialized personnel. The monitor is also suitable for several other types of potentially dangerous apparatus in the medium- and short-wave range.
