Abstract This work presents the preliminary structural and dosimetric analyses of tissue-equivalent Li2B4O7:Ce pellets prepared by solid state synthesis. X-ray diffraction was performed in order to confirm the crystalline phase of Li2B4O7. The dosimetric analyses were done by exposing the pellets to a beta source and using the thermoluminescent technique. The results showed that the thermoluminescent (TL) signals of the pellets present a good reproducibility. The TL peak at 233 °C has negligible fading and the TL dose response is linear in the range from 41 mGy to 42 Gy. These characteristics indicate that the Li2B4O7:Ce pellets produced in this work have potential for use as a thermoluminescent dosimeter.

用于热释光剂量测定的掺铈四硼酸锂

摘要 这项工作介绍了通过固态合成制备的组织等效 Li2B4O7:Ce 颗粒的初步结构和剂量分析。进行 X 射线衍射以确认 Li2B4O7 的晶相。剂量分析是通过将颗粒暴露于 β 源并使用热致发光技术来完成的。结果表明，颗粒的热释光 (TL) 信号具有良好的重现性。233 °C 处的 TL 峰值具有可忽略不计的衰减，并且 TL 剂量响应在 41 mGy 至 42 Gy 的范围内呈线性。这些特性表明，在这项工作中生产的 Li2B4O7:Ce 颗粒具有用作热释光剂量计的潜力。
