[Evaluation of patient exposure to X-ray in view of monitoring carried out in diagnostic laboratories of Lódź region].
X-ray diagnostics, mostly due to a large variety of examinations, and a wide range of its application, is the major source of exposure to ionising radiation in the population. That is why special measurements are being carried out to evaluate the air-kerma values received by patients during X-ray examinations performed most frequently (i.e. lumbo-sacral spine radiography, chest radiography, and thoracic spine radiography). The measurements were performed in 39 different departments (in the Lódź region). The doses received by patients were measured simultaneously using thermoluminescence dosimetry (TLD) and a CONY dosimeter (PTW, Frieburg). In all, 196 measurements were made. The results obtained were compared with the reference levels recommended by the International Agency of Atomic Energy. The study indicates that over 90% of doses received by patients during chest radiography exceeds the recommended level. Of the 39 X-ray departments under control, in 31 the reference levels were exceeded for at least two radiological examinations, which means that in only 20% of departments the radiological equipment and work methodology ensure the acceptable levels of patients' exposure, while the other departments need interventions to explain the reasons why patients receive too high radiation doses, and to eliminate harmful over-exposure.
