This study aims to investigate the thermoluminescence (TL) properties of the YBO₃ sample doped with Nd³⁺, which is known to be an important candidate luminescence material. The Nd³⁺-doped YBO₃ phosphor was synthesized at various concentrations (wt%) utilizing the combustion method. The optimal dopant concentration and optical filter combination for the Nd³⁺-doped YBO₃ samples were determined through analysis of their TL glow curves. Consequently, TL emissions of the specified YBO₃: Nd³⁺ (0.5%) samples were examined using the IRSL-TL 410 nm filter combination. The YBO₃: Nd³⁺ (0.5%) sample displayed two distinct maxima at approximately 210^oC and 390^oC, with a linear heating rate of 2 ^oCs^-1, and when the beta dose response of the sample was examined within the range of 0.1-20 Gy, a consistent linearity (b = 0.946, R²= 0.999) was observed between 0.1-5 Gy. Following 12 cycles of reusability testing, the integrated TL intensity exhibited no significant alterations. A short-term fading experiment of the TL emission of the sample was carried out, and the results showed that up to 7 days, the 1^st maxima faded very little, the 2^nd maxima almost did not fade at all, but around the 7th day, the intensity of this maxima increased greatly.
