Analisa Pengukuran Entrance Surface Dose (ESD) Menggunakan Optically Stimulated Luminescence Dosimeter (OSLD) Pada Pasien Anak

Abstract

The surface dose of radiation in conventional diagnostic radiology exams, also known as the entrance surface dose (ESD), is measured to ensure optimal radiation protection for patients. This study aimed to determine and analyze the doses received by pediatric patients who underwent a chest X-ray examination while being treated in the NICU and PICU rooms at Hermina Karawang Hospital. The research involved measuring the radiation dose in pediatric patients using the OSLD nanoDot. This susceptible device can detect low-dose X-ray radiation exposure, especially in pediatric patients. The study was conducted from September to December 2022 and included 35 patients aged 0 to 5. The results of the ESD measurements received by pediatric patients at Hermina Karawang Hospital in the 0-1 year age group were found to be in line with the DRL (Diagnostic Reference Levels) of the United Kingdom (UK) and Austria, which recommend a range of 0.05 – 0.055 mGy. The average ESD value for this age group was 0.05 mGy. Similarly, for the 1-5 year age group, an average ESD value of 0.048 mGy was obtained, below the UK and Austria DRL range of 0.05 – 0.069 mGy. These results indicate that the ESD received by pediatric patients during thoracic examination at Hermina Karawang Hospital is close to the DRL values recommended by the UK and Austria. However, it is essential to note that regardless of the dose received, it must always be justified and optimized to prevent unnecessary radiation exposure.
