LEAKAGE TEST OF TOSHIBA BRAND CONVENTIONAL X-RAY TUBE TYPE DRX-1603B IN RADIOLOGY INSTALLATION OF RSI SITI RAHMAH PADANG

In the diagnostic radiology quality assurance program, suitability testing is carried out to ensure that the equipment used in diagnostic radiology procedures is functioning properly so that patients do not receive unnecessary exposure According to KEPMENKES No 1250/MENKES/SK/2009, the test frequency is carried out once a year or after repair or maintenance of the X-ray tube house, but until now there has been no conventional X-ray tube leak test at RSI Siti Rahmah Padang since August 24, 2020 by PT Inmed Teknotama Cemerlang. This study aims to determine the procedure for testing tube leaks and to determine whether the results of the Toshiba brand conventional X-ray tube leak test type DRX-1603B at the RSI Siti Rahmah Padang radiology installation exceed the tolerance limit set by the Head of BAPETEN Regulation (Perka) No. 15, 2014

This research was conducted at the Siti Rahmah Padang Islamic Hospital on May 20, 2024. The type of research used in this scientific paper is quantitative research with a Pre-Experimental research design using a one-shot case study design. Data collection was carried out at a distance of 1 meter from the X-ray tube to the surveymeter at the right, front, left, top, back, and bottom points using an exposure factor of 110 Kv, 100 mA and 0.10 s. Data collection was carried out by literature study, observation, experiments and documentation

The results of this study found that the highest leakage value at the right point of the tube, namely the anode section of 9 74 x 10-6 mGy/hour was declared safe because it was still within the radiation leakage value limit, while the lowest leakage value at the top point of 2.04 x 10-6 mGy/hour was declared safe because it was still within the radiation leakage value limit According to the Head of BAPETEN Regulation (Perka) Number 15 of 2014, the radiation leakage value limit is 1 mGy (one milligray) within 1 (one) hour at a distance of 1 m (one meter) with the condition of maximum continuous current strength at maximum kVp.
