1：Experimental Design and Method Selection:

The study used a high-temperature solid-state method to synthesize strontium-doped magnesium tetraborate (MBO) polycrystalline powder. Thermoluminescence (TL) properties were analyzed using a TL reader, with methods including glow curve analysis, dose response measurement, reproducibility testing, and calculation of kinetic parameters via computerized glow curve deconvolution (CGCD) and variable heating rate (VHR) methods.

2：Sample Selection and Data Sources:

Samples were prepared with

3：25 wt% strontium doping, based on previous studies indicating optimal properties. Data were obtained from TL measurements after beta irradiation. List of Experimental Equipment and Materials:

Equipment included a Harshaw QS 3500 Manual type TL reader with S-11 response photomultiplier tube, optical filters from Barr Associates, Inc., an electrical furnace, agate mortar, ceramic crucible, and a 90Sr–90Y beta source. Materials were MgO (Sigma-Aldrich,

4：9% purity), H3BO3 (Sigma-Aldrich, 9% purity), and SrSO4 as the dopant. Experimental Procedures and Operational Workflow:

Starting materials were mixed, ground, heated at 900 °C for 2 hours, doped with strontium, milled for 2 minutes, and reheated at 900 °C for 2 hours. TL glow curves were recorded at a heating rate of 1 °C/s up to 400 °C, with samples irradiated using the beta source. Measurements included dose response from

5：015 Gy to 1150 Gy, reproducibility over 10 cycles, and fading over one month. Data Analysis Methods:

Data were analyzed using CGCD with a program from the Reactor Institute at Delft for kinetic parameters, and VHR method with heating rates from 1 to 8 °C/s. Statistical analysis involved linear fitting for dose response and normalization for reproducibility and fading.
