[An analysis of X-ray diagnostic equipment at Moscow prevention and patient-care facilities]. / Analiz sostoiania parka rengenodiagnosticheskoi apparatury LPU Moskvy.

The paper contains the results of an analytical study held, 2001-2003, at prevention and patient-care facilities of Moscow and dedicated to classification of their X-ray diagnostic equipment (XDE) by models. On the basis of an analysis of typical XDE failures the methodological recommendations for the XDE technical expertise are defined that enable the possibility to evaluate objectively the serviceability of equipment after appropriate repair and to extend its exploitation time over several years without any noticeable worsening in X-ray diagnostics or radiation safety.

[A high-voltage x-ray spectrometer for x-ray apparatus]. / Rentgenospektral'nyi izmeritel' vysokikh napriazhenii dlia rentgenapparatov.

A high-voltage measuring instrument has been developed to be used in medical X-ray equipment. It measures without connection up to the current-carrying circuits. In the device, the limit of the braking spectrum is used to determine the values of X-ray tube-applied voltage, which are calculated to a high precision by the programme put into the analyser and printed out on a printer. The scale of the device is calibrated by the peak reference points of the reference isotopic sources of gamma radiation.
