Borates are appropriate TL materials for radiation dosimetry, because of their equivalence with tissue. Magnesium borate is a tissue equivalent material and its most important advantage over lithium borate, is that this material is insoluble in water. In this work the effect of sintering temperature on the sensitivity of magnesium borate obtained by the solution combustion technique is presented. The results showed that the material doped with Tm and Ag, subjected to 1223 K, for 3 h, had a sensitivity between two and four times higher than that of the commercial dosimeter TLD-100 making it highly appropriate for applications in clinical dosimetry.
硼酸盐是用于辐射剂量测定的合适热释光材料，因为它们与组织等效。硼酸镁是一种组织等效材料，与硼酸锂相比，其最重要的优点是这种材料不溶于水。在这项工作中，展示了烧结温度对通过溶液燃烧技术获得的硼酸镁灵敏度的影响。结果表明，掺杂了铥和银的材料在1223 K下烧结3小时后，其灵敏度比商业剂量计TLD-100高出两到四倍，这使其非常适合临床剂量测定应用。
