[A radiation method of determining the voltage of x-ray radiation generation. Its status and the outlook].

The paper reviews currently available methods for noninvasive determination of the voltage of X-ray radiation generation. It describes their advantages and disadvantages. The technical data of some commercially produced devices are presented. The paper shows it necessary to develop a standard for noninvasive X-ray tube voltage control and describes the main points of the standard presently developed in the framework of the International Electrical Committee 62C.
