After a study of quality control on about 30 radiological equipment and two dark rooms, we are now presenting an analysis of 1806 radiological examinations with 5011 films; the reject is 6.2%, namely 311 films. The analysis of the causes of the reject gives the following results: the more important cause is the error of exposure (52.7% of total reject), followed by geometrical and collimation defects (14.4%) and by the movement of the patient (13.2%). Our results are discussed and compared with other similar data.
