Abstract

This study sought to measure the mean entrance skin dose and third quartile value for paediatric chest x-ray examinations, to find the correlation between mean ESD, age, kVp and weight and compare these to findings and recommendations from other studies. A descriptive, quantitative cross sectional design was used. Thermo luminescence dosimeters placed on the anterior surface of the chest coincident with the primary beam were used to measure radiation dose. Demographic data and exposure parameters were recorded for 20 patients below the age of 5years. The TLDs were read by qualified radiation physicists at the Radiation Protection Authority of Zimbabwe (RPAZ). Data was analysed using SPSS version 16.0 and Microsoft Excel. Entrance surface dose was measured for all patients and the mean dose calculated was higher than those from previous studies in literature. A strong co-relation was found between ESD and weight and also between ESD and age. Results showed that there was a possibility that children were receiving higher doses during chest x-ray examinations as compared to the recommended levels of the ICRP and other previous studies.
