The chemical co-precipitation method was used to prepare Ba_0.88Sr_0.12SO₄:Dy_1.5mol%,Tb_1mol% nanocrystalline powder. Ba_0.88Sr_0.12SO₄:Dy_1.5mol%,Tb_1mol% pellets were fabricated in order to measure gamma ray irradiation. A main TL glow peak around 207 °C, a small peak at 157 °C and a good linear response for doses in the range of 0.01–5 kGy were observed. The TLE spectra of the pellets were recorded at 207 °C. The results of energy response showed that these pellets are energy dependent. The pellets showed fading about 18% during 4 weeks of storage time. The effect of different heating rates on the TL glow peaks of prepared pellets which were recorded after a gamma exposure of 5 kGy was investigated. The intensity of TL glow curves was decreased by an increase in heating rate from 2 °C/s up to 6 °C/s. The dosimetric results showed that the Ba_0.88Sr_0.12SO₄:Dy_1.5mol%,Tb_1mol% pellets could be useful for monitoring gamma radiation for accidental dose assessment.

采用化学共沉淀法制备了Ba _0.88 Sr _0.12 SO ₄：Dy _1.5mol％，Tb _1mol％纳米晶粉。Ba _0.88 Sr _0.12 SO ₄：Dy _1.5mol％，Tb _1mol％制备颗粒以测量γ射线辐射。在0.01-5 kGy的剂量范围内，观察到一个主要的TL辉光峰在207°C附近，在157°C有一个小峰，并具有良好的线性响应。在207℃下记录粒料的TLE光谱。能量响应的结果表明，这些颗粒是能量依赖性的。在储存的4周时间内，颗粒显示约18％的褪色。研究了不同加热速率对制得的小球的TL辉光峰的影响，在γ射线暴露5 kGy后记录了这些小球。TL辉光曲线的强度随着加热速率从2°C / s到6°C / s的增加而降低。剂量学结果表明Ba _0.88 Sr _0.12 SO ₄：Dy _1.5mol％，Tb_1mol％的小球可用于监测伽马辐射以进行意外剂量评估。
