Occupational dose during an interventional radiology procedure

Abstract

The development of radiation utilization, in medical application, increases every year. One of them was the interventional radiology facility. Interventional radiology has been chosen to replace invasive procedures for diagnosing and cure several cases of the blood system. However large radiation exposure for radiation workers remains the main potential of an occupational hazard. Therefore, radiation protection plays an important role in ensuring the occupational dose does not exceed the regulated limits by BAPETEN. The purpose of this study was to determine the estimated effective dose (mSv) received by radiation workers undergoing interventional procedures. Occupational doses were measured using the thermoluminescence dosimeter (TLD) chips which placed on critical organ areas such as thyroid, thorax and gonads / ovaries during interventional procedures. In this study, the interventional procedures carried out for PCI, embolization, PTCA, limb intervention, thoracic intervention and cerebral intervention. The TLD was then read using the TLD Reader 3500 Harshaw. The results of this study showed mean effective dose received by doctors, nurses and radiographers in several hospitals in Indonesia due to carrying out interventional procedures was 0.043 ± 0.034, 0.048 ± 0.064 and 0.047 ± 0.031, respectively. The dose received by the radiation worker is still below the limit regulated by BAPETEN, which is 20 mSv / year. These doses were varied based on the type of interventional procedure and the time of fluoroscopy.
