[Quality assessment of radiological diagnostic examinations from the perspective of radiological protection].

The paper presents current recommendations on radiological protection concerning medical exposure, especially during X-ray diagnostic examinations. Major factors responsible for the level of radiological risk for patients undergoing X-ray examinations are also discussed. (In Poland about 28 million X-ray examinations are performed annually.) A thorough evaluation of 18 X-ray units used in diagnostic laboratories in the Lódź district is presented. It was found that only 6 of 18 X-ray units controlled, satisfy best the evaluation criteria laid down according to the recommendations of the International Atomic Energy Agency (IAEA). The significance of satisfying individual criteria for the achievement of high quality radiological examinations was highlighted.
