[Dependence of the sensitivity of combined intensifying film-screens on the voltage in X-ray tubes].

: The computed and experimental dependencies of the luminescence intensity of intensifying screens, their gain and the sensitivity of the screen-film combinations versus the X-ray tube voltage age compared. The computed data are in good agreement with the experimental results. The data make it possible to account for the hardness in the plots of efficiency for various intensifying screens, when roentgenograms are produced under manual and automated control.
