Dose determination on eyes and thyroid in X-ray diagnostic of children with RPL and TL dosimeters

Diagnostic radiology is the main source of exposure of the population to man-made ionising radiation. The X-ray examinations of thoracal organs occupy the first place, particularly in childhood. To reduce the risk from exposure in diagnostic X-ray examinations, especially paediatric diagnostic, the knowledge of the absorbed doses in tissue is important. Long-term and highly statistical dose measurements on patients and various phantoms during thoracal diagnostics of children with various dosimetric systems were described in the literature. The aim of the recent work was to measure the skin doses during X-ray diagnostic of lung of children, first of all on the eyes, the thyroid gland and gonades with radiophotoluminescence glass (RPL) and thermoluminescence (TL) dosimeters. Eyes and thyroid are radiosensitive organs and they are in the primary beam during the diagnostic treatment. In addition to dosimetry measurements cytogenetically status of patients was investigated. In the study special attention was given for use of adequate protection devices. Radiation risks associated with paediatric patients may not be considered as trivial. The present data should be taken into adequate radiation protection during X-ray examination, although we expected very low doses. On the basis of the results some proposals for the protocol of X-ray diagnostic of thorax will be given.
