[An experience of using the DRK-1 dosimeter with conduit ionizing chamber for monitoring the parameters of X-ray diagnostic equipment].

An experience of using, at the State Sanitary and Epidemiologic Supervision (SSES), the Control X-ray Dosimeter (DRK-1) to calculate the dose-square product in the radiation-and-hygienic evaluation of medical X-ray units of different types is described in the paper. The qualitative evaluation monitoring applicable to X-ray equipment is based on the finding and subsequent analysis of graphic dose-square relationships, i.e. anode voltage(measured manually or by X-ray exposure meter), exposition time, anode current, and current-time product. Real graphs for both normally functioning and for malfunctioning units are depicted. The unit radiation output is described.
