The article analyzes the data of state statistical observation for the period from 2011 to 2015. The analysis of the indicators of the number of radiation diagnostic devices, namely, radiographic apparatus, computer tomography and magnetic resonance tomography, the number of studies carried out on them and the number of radiologists working on this equipment. The load on each device in different regions is determined. The most effective regions for the use of the fleet of radiation diagnostic equipment and their congestion have been determined. The results of the study confirm the hypothesis that the effectiveness of the operation of the radiation diagnostics service does not depend on the amount of equipping the equipment of the regions with radiation diagnostic devices. This study made it possible to identify regions with the maximum and minimum efficiency of the operation of the radiation diagnostics service.
