Object of study: effective doses of "standard" patients in various types of X-ray diagnostic examinations, radiation risks from medical diagnostic exposure. Purpose: evaluation of the collective effective doses and radiation risks of the population in Ukraine from the most common types of X-ray diagnostic examinations and determination of the ways to their reduction. Methods and equipment: semiconductor and thermoluminescence dosimetry, methods of mathematical statistics; method of phantom simulation (mathematical and physical phantoms), thermoluminescence unit PCL-3, universal dosimeter Piranha 657, ionization dosimeter DRTS-01, anthropomorphic heterogeneous phantom of "standard" patient. Theoretical and practical results: the estimation of the organ and issue equivalent doses distributions for the "standard" person by means of phantom simulation the conditions of patients irradiation for the 8 main types of X-ray diagnostic examinations. The effective doses and conversion factors from dosimetric values, which are controlled in practice, and effective and equivalent doses are determined. The results are confirmed by 116 phantom simulations on 10 X-ray units of different models. Novelty: for the first time in Ukraine, the collective effective doses of the Ukrainian population were determined based on the results of the assessment the effective doses of "standard" patients and the questionnaire data on the structure of X-ray diagnostic procedures in the country. The absolute and attributive radiation risks of medical diagnostic radiation in the Ukrainian population were assessed, and the approaches to dose reduction were proposed. Effectiveness of implementation: the analysis of attributive radiation risk the distribution for oncological diseases of different organs and tissues will allow to predict the consequences for the health of patients. Applications: radiation hygiene, X-ray diagnostics.
