Sažetak
Radiodiagnostic examinations of children present particular importance from the radiation hygiene point of view. The estimation of the radiation load of paediatric patient is not easy, because of the lack of information about organ weighting factors for various ages of patients, as well as due to the differences in applied X-ray examination parameters. In the district of Slovak Republic, in which also the working NPP Jaslovske Bohunice is included, we have tried to estimate the radiation load of children to 15 years by chest radiodiagnostic examinastions. Our data of entrance surface doses were collected using measurements with TLD for 100 patients divided in 5 age categories at six radiodiganostic departments. The calculations of the total absorbed dose were performed using the measured ESD values integrated over the X-ray beam area, the conversion factors between the imparted energy and the dose-area product and the known irradiation parameters (kV, HVL, mass, etc.). The analysis of the obtained absorbed doses (Ea) as a function of age for chest PA radiodiagnostic examinations has shown, that the investigated Slovak radiodiagnostic centres use rather lower voltage techniques and the entrance surface doses are much higher than the proposed value of EC.
