Efektivitas Penggunaan Pendose dalam Mengevaluasi Nilai Dosis Radiasi Petugas pada Operasional Alat C-Arm Di Rumah Sakit Umum Daerah Al Ihsan Pemprov Jawa Barat

Abstract

Background: The use of C-Arm in interventional radiology procedures has,potential to expose both patients and radiation workers to ionize the radiation. Therefore, radiation dose monitoring is essential to ensure occupational safety in accordance with radiation protection principles. This study aimed to evaluate the radiation dose received by radiation workers using a personal dosimeter (Pendose) and to measure the output dose of the C-Arm device at  Al-Ihsan General Regional Hospital, West Java.

Methods: This research employed a descriptive quantitative method with direct data collection from 64 examinations involving 10 radiographers. The data recorded included C-Arm output dose (mGy) and personal dose measured with Pendose (µSv) after each procedure. Descriptive statistical analysis was conducted, including mean, minimum, maximum, and standard deviation values, and data visualization was presented in the form of comparative and distribution charts..

Results: The results showed that the mean C-Arm output dose was 52.8 mGy (range 0–1226.6 mGy; SD = 187.2), while the mean Pendose dose was 0.52 µSv (range 0–18.3 µSv; SD = 2.26). Most examinations produced low radiation doses, but some procedures showed extreme values. The histogram indicated that the majority of doses were distributed within the lower range, with a few outliers in certain cases.

Conclusions: The radiation doses received by workers were relatively low and within safe limits, which is likely due to the short fluoroscopy duration and appropriate imaging techniques. Nevertheless, the presence of high-dose variations in several cases highlights the importance of continuous dose monitoring and the application of the ALARA principle in clinical practice.
