Effective Dose Evaluation for Chest and Abdomen X-ray Examinations

Taha M. T., Kutbi R. A., Allehyani S. H.

Abstract: Background The aim of this study was to estimate effective dose (ED) via the indirect measurement of the entrance surface dose (ESD) to patients undergoing chest and abdomen examinations in Hera General Hospital (HGH). Material and MethodsThe ESD per examination was calculated from X-ray dose out put measurements at 80 KV, 10 mAs and tube output parameters for a patient sample size of thirty eight cases conducted X-ray units at HGH. Effective doses (ED) were then estimated using ED/ESD conversion factors based on ICRP-103. ResultsHospital mean ESD for chest posterior anterior was 0.126 0.027 mGy and for abdomen anterior posterior was 1.89 1.14 mGy. The mean effective doses for chest posterior anterior and abdomen anterior posterior were 0.02 mSv and 0.25 mSv respectively. Indirect measurement of ESD is easier than measuring ESD directly for reasons related to patient collaboration. Conclusions Hospital mean ESD for chest posterior anterior was 0.126 0.027 mGy and for abdomen anterior posterior was 1.89 1.14 mGy. The mean effective doses for chest posterior anterior and abdomen anterior posterior were 0.02 mSv and 0.25 mSv respectively. Indirect measurement of ESD is easier than measuring ESD directly for reasons related to patient collaboration.
