<p>Liquid scintillators are widely used in nuclear, particle, and medical physics, as well as in other radiation-related applications. Traditional liquid scintillators typically consist of organic solvents and fluors. In this study, a new acetone-based liquid scintillator was synthesized by dissolving 2,5-diphenyloxazole (fluor) in acetone, replacing conventional oil-based solvents. A new acetone-based scintillation solution mixed with a contrast agent was prepared to enhance X-ray attenuation properties. The performance of this new formulation was evaluated by measuring Hounsfield unit values using computed tomography. Specifically, Hounsfield unit values for several scintillator samples were obtained from computed tomography images and compared with those of traditional scintillator solutions. Our new liquid scintillation formulation with a contrast agent concentration of 50% or higher achieves Hounsfield unit values exceeding 2500. This formulation enables the detection of radiation exposure via its fluorescent properties, enhancing radiation safety monitoring, while also providing a liquid shielding effect. To date, no prior research or results have reported on this specific combination of acetone, fluor, and contrast agent. These findings suggest that new acetone-based scintillation solution mixed with a contrast agent has potential applications in dosimetry, radiation shielding, and imaging analysis.</p>
