The gas leak in Chimaera near Çıralı, Antalya, has been active for thousands of years. It is also known to be the source of the first Olympic flame in the Hellenistic period. The sample taken from the Chimaere seepage annealed for thousands of years was determined to be calcite-magnesian (Ca, Mg)O . In this study, thermoluminescence (TL) properties of calcite-magnesian annealed for thousands of years in the fire caused by methane gas were investigated for particle size, dose-response, heating rate, and fading experiments. It exhibits a clear TL glow curve with two distinct peaks positioned at 160 and 330°C, and its shape is not affected by variation in applied dose and reproduciility of experiment. There is a wide linear relationship between TL output and applied dose up to 614 Gy. Although the positions of the TL peaks are stable with the cycle of measurement, a poor reusability was observed in terms of the area under the TL glow curve and peak intensity.
奇美拉气田位于土耳其安塔利亚的切雷利,其甲烷泄漏已经活跃了数千年。这里也是古希腊时期采集第一届奥运圣火的地方。对从奇美拉渗漏处采集的经过数千年退火的样本进行分析,确定其为方解石-镁(Ca,Mg)O。在这项研究中,研究了在甲烷火灾中退火数千年的方解石-镁的热释光(TL)特性,包括粒度、剂量响应、加热速率和退色实验。结果表明,该物质在 160 和 330°C 处有两个明显的峰值,呈现出清晰的 TL 发光曲线,其形状不受施加剂量和实验重现性的影响。TL 输出与施加剂量之间存在广泛的线性关系,最高可达 614 Gy。尽管 TL 峰的位置在测量周期中是稳定的,但从 TL 发光曲线的面积和峰值强度来看,其可重复使用性较差。
