This study aims to analyze the spatial distribution of doses and dose rates of digital radiography X-ray radiation at a height of one meter with variations in trajectories and distances from the scattered radiation source. Measurements were conducted in the radiology installation of Hospital X using a digital X-ray radiography unit and a RaySafe X2 surveymeter with a phantom as a patient representation. Data were collected on six measurement trajectories with varying distances of one meter and two meters from the radiation source. The highest dose value of 0.001319 mSv was obtained at a distance of one meter, while the lowest dose of 0.000212 mSv was recorded at a distance of two meters. The distribution of radiation exposure was visualized using Surfer software in the form of an isodose contour map. The results showed that the highest doses and dose rates of radiation were concentrated around the radiation source and decreased with increasing distance, in accordance with the inverse square law. This spatial visualization provides a comprehensive picture of the scatter radiation distribution pattern as a basis for radiation safety evaluation and radiation protection optimization in the radiology room.
