This work presents results obtained following the preparation of lithium borate by the chemical reaction between lithium carbonate (Li₂CO₃) and boric acid (H₃BO₃), doping the host salt of lithium borate (Li₂B₄O₇) with ions of copper, silver and phosphorus. With the obtained material dosimeters were produced in sintered pellet form which were exposed by gamma radiation that emitted from ⁶⁰Co source. The highest sensitivity was found for the sample of Li₂B₄O₇:Cu,Ag,P (in pellet form) with 0.45, 0.45 and 12 mol% of Cu, Ag and P, respectively, subjected to a thermal treatment at 1123 K during 2 h. The TL response shows linearity in the dose range from 0.005 to 100 Gy. The lower detection limit (LDL) was equal to 6.10 μGy. The fading was found to be 3% in the first ten days and 9% at the end of thirty days. The repeatability of TL measurements for twenty cycles, showed a variability coefficient equal to 4.15%. The glow curve shape of Li₂B₄O₇:Cu,Ag,P sintered pellet shows two peaks with general-kinetics order. This new material could be appropriate for dosimetry in clinical radiation applications.

这项工作介绍了通过碳酸锂（Li ₂ CO ₃）与硼酸（H ₃ BO ₃）之间的化学反应制备硼酸锂后，将硼酸锂（Li ₂ B ₄ O ₇）的主体盐掺杂而获得的结果。铜，银和磷的离子。用所获得的材料，以烧结的丸粒形式产生剂量计，该剂量计被从⁶⁰ Co源发射的伽马射线曝光。Li ₂ B ₄ O ₇样品的灵敏度最高：分别具有0.45％，0.45％和12 mol％的Cu，Ag和P的：Cu，Ag，P（颗粒形式）在2小时内于1123 K进行热处理。TL响应在0.005至100 Gy的剂量范围内显示线性。检测下限（LDL）等于6.10μGy。发现褪色在开始的十天内为3％，在三十天内为9％。TL测量在20个循环中的可重复性，其变异系数等于4.15％。Li ₂ B ₄ O ₇：Cu，Ag，P烧结球团的辉光曲线形状显示出两个峰，具有一般动力学顺序。这种新材料可能适用于临床放射应用中的剂量测定。
