查明铀元素在矿石、岩石光片和薄片表面的含量及其分布特征,是岩矿工作的重要课题。目前通常采用X光干板及核乳胶照相方法。以上方法各有优点,但也有不足之处。两种方法都很难精确地确定样品表面铀含量的变化,而核乳胶照相方法的不足之处是限于测定低或超低含量样品(n·ppm;n·ppb)。本文介绍的自然蜕变径迹检测方法,可比较精确地确
Identifying the content and distribution characteristics of uranium in the surface of ore, rock light sheet and flake is an important issue for rock and mine work. Currently commonly used X-ray dry board and nuclear latex camera method. The above methods have their own advantages, but there are also shortcomings. Both methods make it difficult to accurately determine the change in uranium content on the sample surface, whereas the drawbacks of the nuclear latex method are limited to the determination of low or ultra-low content samples (n · ppm; n · ppb). This article describes the natural metamorphic track detection method can be more accurate indeed
