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.

烧结温度对固溶燃烧法获得的MgB 4 O 7:Tm,Ag敏感性的影响
由于硼酸盐与组织相当,因此硼酸盐是用于辐射剂量测定的合适TL材料。硼酸镁是一种组织等效材料,与硼酸锂相比,它最重要的优点是该材料不溶于水。在这项工作中,提出了烧结温度对通过固溶燃烧技术获得的硼酸镁敏感性的影响。结果表明,掺有Tm和Ag的材料在1223 K下处理3 h,其灵敏度是市售剂量计TLD-100的2至4倍,这使其非常适合于临床剂量学。
