Medical exposure to x-radiation in Poland

Risk to patient in medical exposures has been under discussion for a number of years, as it is main man-made source of irradiation for population in the most of countries advanced in technology; especially, medical X-rays are the major contributor to population dose.This paper presents the results of national survey of X-ray diagnostics, which was based on data of 1995. For the most frequent examinations the doses to patients have been evaluated by means of theoretical computational method - Monte Carlo simulation.A special problem is interventions radiology procedures during which patients can receive high doses.
