Panoramic is an extra oral examination that can produce an image of the entire mouth in a single exposure to speed up the examination. However, a panoramic examination takes several seconds until the collimator finishes surrounding the object. Therefore, knowing how to properly use self-protective devices and monitor radiation exposure is necessary to optimize radiation safety control. This study aims to analyze the feasibility of using mobile shielding as self-protection during exposure to a panoramic examination. This study was conducted at Koja Hospital in February - June 2023 using an analytical, quantitative method to measure the exposure dose rate in the panoramic room of Koja Hospital. Measurements are made using a calibrated survey meter measuring instrument. The result of measuring the initial exposure at a distance of 100 m is 84.19 µSv. Data analysis shows that the exposure received by radiation workers is far from the established dose limit value, so mobile shielding used as a self-protective device in the panoramic room of Koja Hospital is still worth using with high-efficiency values of 99.16% and wood+Pb at 99.14%. Although the rate of exposure dose received is still far from the dose limit value, workers should be careful when using radiation to minimize health risks.
