Analysis of Neonatal Radiographic Examination Entrance Surface Dose (ESD) and Scattering Dose (SD)

Abstract

Diagnostic radiology is also used in the assessment and treatment of neonates. Radiographic examinations are often used to assess the development of the lungs and internal organs of the abdomen with medical abnormalities in infants. This study aims to analyze the dose of surface radiation in infants and the dose of scattered radiation during a radiographic examination in the Neonatal Intensive Care room at a hospital in East Jakarta. The research method used is experimental based on quantitative data processing to determine the surface dose received by the baby and the scattered radiation dose during radiographic examination. The measuring instrument used is the Thermoluminescence Dosimeter (TLD) for the surface radiation dose and the Survey meter for the scattered radiation dose. The dose of surface radiation obtained from 6 infant patients was still above the recommended dose. The dose ratio obtained is between 1.9–3.36 times the UNSCEAR dose. Meanwhile, the scattered radiation dose produced is below the Dose Limit Value set by BAPETEN.
