This study was performed to measure the entrance surface air kerma (ESAK) for optimisation of chest X-ray examination of children in general radiography hospitals in Khartoum. ESAK was estimated using the X-ray tube output exposure and patient-specific exposure parameters collected during routine examinations. The estimated ESAK values per radiography ranged from 17 to 89 μGy, 32 to 161, 67 to 242, 77 to 278; and from 95 to 389 μGy for Newborn, 1, 5, 10 and 15 y children, respectively. Doses are comparable with a previous study and are somewhat higher than the UK reference dose levels. The study demonstrated the necessity to follow guidelines for quality radiograph as a key element in the optimisation of X-ray examination of children. Frequent dose measurements are of particular importance for the optimisation of X-ray examination of children in general radiography hospitals.
