Radiation protection of children in x ray diagnostic

Pulmonary radiograms represent the majority of radiological examinations. For evaluation of the children exposure the measurement of the radiation dose in X ray diagnostic is needed. In our study doses were measured in routine X-ray diagnostic of chest with thermoluminescent (TLD) and radiophotoluminescent (RPL) glass dosimeters. The irradiation conditions selected were that most commonly used for children examinations of thorax. In addition to common radiation protection devices (thyroid collar, gonad protection) for small children special “baby-fix” and /or rotation chair were used. Radiation doses have been determined on various parts of the body on 50 patients of five age groups during thorax examinations. At standard projections of lung examinations, the highest radiation doses have been measured on the back (0.26±0.11 mSv). The large standard deviation has been caused by a series of factors (the irradiation conditions, different X-ray equipment, patient’s' physical characteristics, work methods etc.). The influence of the work method of 3 radiology technicians was studied on 60 patients. This study on children patients during X-ray diagnostics of chest has showed that: a) Dosimetry measurement in every day X-ray diagnostic is useful to show the possible deficiency in radiation protection measures, b) The dose on patients depends also on the human working method. Adequate education of technicians can improve the radiation protection of patients.
