根据热释光测量结果,用敏化修正方法计算了湖光岩玛珥湖周围岩洞内的火山灰的古剂量。用330℃附近的热释光峰作为剂量响应计算出的结果为(75.3±4.8)Gy,但取400℃附近的热释光作为剂量响应计算出的结果为(115±8)Gy。建立物理模型分析了这两种结果不同的内在原因。
Based on the thermoluminescence (TL) data, the paleodose of volcanic ash near Huguangyan Maar Lake was calculated with sensitized revision technique. The calculated paleodose depending on TL about 330 ℃ is (75.3±4.8) Gy, while the calculated paleodose depending on TL about 400 ℃ is (115±8) Gy. A physical model is set up to analyze the difference between the two results.
