Abstract

The "As Low As Reasonably Achievable" (ALARA) principle says that patient safety is the most important thing in diagnostic radiography. Reject and Repeat Analysis (RRA) is a reliable way to check quality because it finds technical and operator-related mistakes that lead to unnecessary radiation exposure. Since the X-ray tube is the most important part of making images, it is important to choose the right tube settings, especially the kilovoltage peak (kVp), to get images that are good enough for diagnosis while lowering the dose. This study examined radiographic rejections and repetitions at Plateau State Specialist Hospital over the course of one year, during which 2,705 radiographs were evaluated. The overall reject and repeat rate were 4.99%, which is within the internationally acceptable threshold of 5–10%. The chi-square analysis demonstrated that reject and repeat rates are not significantly influenced by the examination type. The results also indicate that errors are systemic rather than confined to specific examinations. The strong positive correlations show that workload is a big factor in radiographic errors. These findings highlight the importance of optimizing x-ray tube parameters and maintaining continuous RRA to ensure effective radiation protection and improved diagnostic outcomes.
