Differences in using the international commission on radiological protection's publications 60 and 103 for determining effective dose in paediatric CT examinations

Abstract

The use of computed tomography (CT) worldwide is continuing to increase for both adults and children, posing population health risks due to radiation exposure. These risks are highest for children, reducing with age at exposure. Effective dose is a useful parameter for expressing relative risk and comparing dose. In this study, high sensitivity thermoluminescence dosemeters (TLD) were used to measure organ absorbed doses and to calculate effective dose for paediatric CT examinations of the brain, chest and abdomen/pelvis. Formalisms recommended by the International Commission on Radiological Protection (ICRP) in Publications 60 and 103 were assessed. The effective dose computed using ICRP 10..
