Concern about the radiation dose to children from diagnostic radiology examinations stems from the observation that IAEA HUMAN HEALTH SERIES No. 24 SERIES No. IAEA HUMAN HEALTH children can receive doses in excess of those delivered to adults, in part due to the digital nature of image receptors that may give no warning to the operator of the dose to the patient. This concern should be extended to the broad range of paediatric diagnostic radiological procedures responsible for radiation dose in children, especially as factors including increased radiosensitivity and the longer life expectancy of children increase the associated radiation risk. Dosimetry for paediatric patients undergoing diagnostic radiology requires special consideration in addition to the general dosimetric methodologies used for adult patients. This publication informs health professionals about standardized methodologies to determine paediatric dose for all major modalities, such as general radiography, fl uoroscopy and computed tomography.
