Abstract Objective To measure the entrance surface dose (ESD) in various paediatric radiological examinations and compare them with the existing diagnostic reference levels (DRLs).Methods Measurements of ESD using thermoluminescent dosemeters were carried out in a sample of 255 paediatric patients who underwent various common radiological examinations (chest, skull, pelvis, full spine). The patients were categorized according to age, and the mean ESD was calculated for each examination and age category. Additionally, the effective doses were estimated from measured ESD using appropriate conversion coefficients found in the literature.Results The mean ESD values were found to be well below the proposed DRLs for all the examinations studied except for the chest.Conclusion Even in examinations that did not exceed the DRL, measures should be taken to reduce unnecessary radiation doses.
