Results of a Dosimetry Study in the European Community on Frequent X Ray Examination in Infants

Abstract

This Europe-wide dosimetry study, covering 89 departments in 11 EC countries, measured entrance surface dose (ESD) using TLDs, and surveyed X ray equipment and radiographic techniques used for frequent paediatric X ray examinations of the chest, abdomen, pelvis, skull and spine. The survey was limited to infants (10 months, 4 months and prematures of ∼ 1 kg). Data analysis shows that radiographic techniques differed widely. This was one of the reasons for the large variations in ESD of an order of magnitude of 1:50. A substantial number of departments used either very old X ray generators and/or techniques which are poorly suited for paediatric radiology. A significant dose reduction was seen when recommended guidelines for good radiographic technique were followed. The results of this study emphasise the necessity for the adherence to easily followed guidelines for the improvement of training and equipment in paediatric radiology.
