| dc.description.abstract | Background Radiation exposure at the early stage of life usually results in a likelihood of two or three fold increase in lifetime risk for certain detrimental effects compared with that of adult. Radiation protection in pediatric radiology requires special attention because children are more sensitive to radiation and at higher risk than adults. The objective of this study is to assess variation of ESD in conventional and digital radiography in pediatrics age group of some hospitals in Addis Ababa, Ethiopia. Method Prospective cross sectional study was conducted using convenience sampling; data were collected, checked for clarity and completeness and entered into SPSS version 23 for analysis. The data were analyzed Result statistically, and compared with the international reference dose values. Out of 620 study participants 309 (49.8%) were exposed to conventional radiograph while 311 (50.2) were exposed to digital radiograph. Calculation of ESD shows that mean ESD of conventional radiograph to be 1.13, while that of digital radiograph is 1.84. The third quartile of Conventional is 1.72 and that of digital radiography is 0.92. In age group 5-15 digital radiography ESD’s are greater than conventional ESD’s, while in those less than 5 years conventional radiography ESD’s are higher than that of digital ESD’s. In abdomen, extremities, pelvis and spine digital radiograph ESD’s are higher than conventional ones but in CXR and skull those of conventional ones are higher than digital radiograph ESDs. Conclusion According to this study, radiation dose (mean ESD) is relatively higher in conventional radiography in chest x ray and skull when compared to Digital Radiography whereas in abdomen, extrimities, pelvis and spine digital radiography mean ESDs are higher than conventional radiography mean ESDs | en_US |
