【摘要】 报道了铀矿脉中石英热释光强度随放射性元素含量增加而降低的异常现象。从高能辐射作用于物体时的两种效应入手，分析讨论了异致热释光强度降低的原因。石英热释光的发光曲线特征揭示了铀矿脉形成的热历史。根据铀、钍、钾含量，计算了铀矿脉中岩矿石的放射生热率，并讨论了石英热释光强度与放射生热率的关系。更多还原

【Abstract】 This paper reports the anomalous phenomenon that quartz thermoluminescence intensity is reduced with increasing contents of radioactive elements in uranium bearing veins. The reduction mechanism of thermoluminescence intensity is studied in terms of two sorts of effects induced by the action of high - energy radiation on objects. The thermoluminescence patterns of quartz revealed clearly the thermal history during the formation of the uranium veins. From the contents of uranium, thorium and POtassium, radiogenic heat producing ratios were calculated for rocks and ores of the uranium vein, and the relation between quartz thermoluminescence intensity and radiogenic heating rate is discussed.更多还原
