Radiology Patient Dosage Monitoring for Local Diagnostic Reference Level

The utilization of radiation for health in Indonesia shows a significant increase, it can be seen from the increasing number of modalities of ionizing radiation sources used and the types of medical actions carried out with the help of radiation. The use of radiation must be monitored to ensure the protection and safety of workers, patients, and the community. In Government Regulation No. 33/2007 which regulates radiation safety for workers, the community and the environment, it can be seen that one of the protection requirements that must be met in the utilization of radiation is the optimization of radiation protection and safety. In diagnostic and interventional radiology, optimization can be interpreted as an attempt to make the dose received by patients as low as possible while maintaining optimum image quality. In this study, the effort to optimize patient dose is carried out on general radiography with the application of Si-INTAN (National Patient Dose Data Information System). The Si-INTAN portal is used as a means for monitoring patient dosages and the preparation of local and national Diagnostic Reference Level (DRL). The results showed that DRL is one of the patient's dose monitoring instruments. Local DRL value of Kasih Ibu Kedonganan Hospital for PA (Postero Anterior) projection in babies 0,381mGy, children 0,412 mGy and adults 0,418 mGy. This DRL value is a reference to determine the value of the National DRL.
