Leakage Test of Conventional X-Ray Tube in Radiology Installation of Regional Hospital Prof. H. Muhammad Yamin, Sh

Abstract

Quality Assurance, or QA, encompasses the overall management of a program to ensure excellence in medical care and ensure radiological health services. One component is Quality Assurance, or QC, which includes acceptance testing, routine performance monitoring, and error correction. The goal is to determine whether there are any leaks and whether the leak value exceeds the pass-through value set by BAPETEN (≤ 1 mGy/hour) for conventional X-ray machines. This quantitative research using an experimental method was conducted in the Radiology Unit of Prof. Muhammad Yamin, S.H. Pariaman Regional Hospital in June 2025. The exposure factor used was 102 kVp and 50 mA at a distance of 1 meter. The X-ray dose rate was measured using a Raysafe survey meter. The exposure process was repeated three times and then averaged. The average value was then subtracted from the background. The dose rate value was then calculated using the Leakage formula to determine the leakage value. In this study, the results of leakage on the right side were 8.316 x 10-4, the front side was 9.174 x 10-4, the left side was 5.742 x 10-4, the top side was 1.353 x 10-3 and the bottom side was 1.1154 x 10-3. The tube leakage value in this study was still in the category of passing test value ≤ 1 mGy/hour. Based on these results, it can be concluded that the conventional x-ray tube in the radiology installation of Prof. Muhammad Yamin, S.H Pariaman Regional General Hospital experienced leakage but the value did not exceed the passing test value set by BAPETEN. Therefore, the right, front, left, top and back sides of the tube were declared safe.
