Conventional radiography practices using X-rays have been a crucial radio-diagnostic tool for detecting internal organ ailments, malformations and disease conditions in humans and animals for many years. This study was performed to evaluate the accuracy and reproducibility of kVp in X-ray machines installed in selected hospitals in Abuja as a measure to ensuring that the radiation doses selected are the ones delivered to patients. The result for kVp accuracy for machines XM-1, XM-2, XM-3, XM-4 and XM-5 shows average percentage error of 1.83%, 1.83%, 2.03%, 3.03%, 1.29% and 2.40% respectively which are within the tolerance limit of ±5 % while the kVp reproducibility of the machines XM-1, XM-2, XM-3, XM-4 and XM-5 exhibit values of 0.39%, 0.32%, 1.64%, 0.10% and 0.07% respectively and these are also within the normal limit of tolerance of less than ±5%.
