General radiographic patient dose monitoring using conformity test data

Abstract

Currently, the Nuclear Energy Supervisory Agency (BAPETEN) is actively guiding users or license holders related to patient protection against radiation hazards or often referred to as radiation protection and safety on medical exposure. Protection against medical exposure became a big issue when the mandatory compliance test on X-ray equipment for diagnostic and interventional radiology was introduced. In addition, license holders through their medical practitioners are also required to use the level of medical exposure guidelines. While PERKA BAPETEN No. 9, 2011 concerning the Suitability Test of Diagnostic and Interventional Radiology X-Ray device, states that one of the test parameters that directly affect the patient's radiation dose and determine the feasibility of operating the X-Ray device to the patient is information on the dose or rate of radiation dose received by the patient. Monitoring doses with Entrance Surface Air Kerma (ESAK) or what is often referred to as ESD (entrance surface dose) using suitability conformity test data starting from 50,60,70,80,90 and 100 kVp with 20 mAs at SID 100 meters. The results of the research on the value of ESAK was 0.049 mGy, an ESAK value that still met the national I-DRL value from BAPETEN Regulation No. 1211/K/V/2021.
