    • An aspect of the present invention is directed to a system for use in oil well drilling applications. The system includes a scintillator material having a cubic garnet host and praseodymium distributed within the host. The scintillator material emits ultraviolet radiation in response to stimulating gamma ray radiation. A radiation detector optically coupled to the scintillator detects the emitted ultraviolet radiation. Another aspect of the invention is a method for detecting oil. A radiation detector is optically coupled to a scintillator material having a cubic garnet host and praseodymium distributed within the host, wherein the praseodymium acts as an activator, and wherein the scintillator material emits ultraviolet radiation in response to stimulating gamma ray radiation. The detector and the scintillator material are lowered below the surface of the earth, and ultraviolet radiation emitted by the scintillator material in response to stimulating gamma ray radiation reflected by hydrogen bearing compounds indicating the presence of oil is detected by the detector.
    • 本发明的一个方面涉及一种用于油井钻井应用的系统。 该系统包括具有分布在主机内的立方石榴石主体和镨的闪烁体材料。 闪烁体材料响应于刺激的γ射线辐射而发射紫外线。 与闪烁体光学耦合的放射线检测器检测发射的紫外线辐射。 本发明的另一方面是检测油的方法。 放射线检测器光学耦合到具有分布在主机内的立方石榴石主体和镨的闪烁体材料,其中镨作为激活剂,并且其中闪烁体材料响应于刺激的γ射线辐射而发射紫外线辐射。 检测器和闪烁体材料降低到地球表面以下,并且由检测器检测响应由表示油存在的含氢化合物反映的刺激性伽马射线辐射而由闪烁体材料发射的紫外线辐射。
