一般说来,根据γ能谱测量所得到的铀、钍和钾含量比值,很容易确定铀异常的意义。此种方法适合从飞机上和汽车上进行遥测,也可用于步行测量,并能对所采集的样品进行检查。当前,为了满足铀矿普查者的要求,已经专门设计了大量可供选择的γ能谱仪,将来会设计出更小、更好的仪器供使用.但是,只有在使用体积足够大的闪烁晶体的情况下,才能对放射性元素进行有统计意义的测定,因此对任何适用的γ能谱仪的尺寸和重量的限制要求都是较低的。轻便y能谱仪的成功应用,将取决于在世界主要铀矿区或其附近的远景地区能否提供合适的校正模型。将来快速解释铀异常的可能性,在很大程度上取决于数字计算机的效率。
In general, the significance of uranium anomalies can easily be determined on the basis of the ratios of uranium, thorium and potassium obtained by gamma spectrometry. This method is suitable for telemetry from airplanes and cars, as well as for walking measurements and for examining collected samples. Currently, in order to meet the requirements of uranium census investigators, a large number of γ spectrometers have been specially designed and in the future smaller and better instruments will be designed for use. However, only using scintillation crystals of sufficient size , A statistically significant determination of the radioactive elements is made and therefore the size and weight limitations of any applicable gamma spectrometer are low. The successful application of a portable gamma spectrometer will depend on the availability of a suitable calibration model in the foreground at or near the world’s major uranium mines. The possibility of a quick interpretation of uranium anomalies in the future depends to a great extent on the efficiency of digital computers.
