Abstract
This study evaluated the current radiation techniques and dose levels employed in pediatric chest radiography at Union Diagnostics, Lagos State, Nigeria. A descriptive cross-sectional survey design was utilized, involving 80 participants comprising radiographers (68.8%), radiologists (12.5%), and radiographic technologists (18.8%). The findings indicated that the most frequently reported Dose-Area Product (DAP) values ranged between 40–80 mGy·cm² for infants and 80–120 mGy·cm² for older children. Majority of respondents reported using tube voltage settings of 60–80 kVp (81.3%) and exposure factors between 1–5 mAs (87.5%). Furthermore, 87.5% of participants demonstrated familiarity with the ALARA (As Low As Reasonably Achievable) principle, with 81.2% indicating consistent application in practice. Patient age and body size were identified as the predominant determinants of variations in radiation technique (93.8%). The study revealed considerable variability in pediatric chest X-ray practices and underscores the need for the standardization of imaging protocols, implementation of evidence-based dose optimization strategies, and continuous professional development to enhance image quality and ensure pediatric patient safety.
