ABSTRACT

Purpose: To estimate the technical condition of the ӭray machine park in Moscow, according to the establishment of patient exposure levels from the technical condition.

Material and methods: Radiation monitoring of physical and technical parameters of X-ray machines, patient dose assessment due to X-ray studies.

Results: The evaluation of the technical condition of x-ray park of Moscow, the assessment of radiation exposure of patients for 1998-2013 is given. The dependence of radiation doses of patients from the technical condition of the X-ray diagnostic apparatus was estimated. It is established that the patient radiation dose should be evaluated in each case, and the use of averaged (tabular) values leads to significant distortions during the assessing radiation exposure. One of the main aspects of ensuring radiation safety of patients is the implementation of the principle of optimization: the maximum possible decrease in exposure to patients while maintaining appropriate quality diagnostic information. The crucial thing in the implementation of this task is played by the staff understanding the need to reduce the radiation doses of patients, the influence of the technical condition of the equipment at the radiation exposure and the implementation presented in the paper approaches into everyday practice.

Summary: Analysis of the results shows that the dose of irradiation of patients from 1998 to 2013 decreased by more than 2.5 times. Reduced radiation exposure associated with the decommissioning of the X-ray machines that do not meet the requirements of the applicable regulations, the introduction of digital technology, the introduction of patient dose monitoring during radiological procedures.

Keywords: X-ray radiation, patients, effective radiation doses, radiationhygienic passport, fluoroscopy, radiography, CT scan
