用一种十分轻便的源来激发X-射线荧光的分析仪进一步得到了发展,它可以在工作面上现场探测和定量测定微量金的含量。这技术是利用Cd发出的88Kevγ射线去激发金的KβX射线,并用仪器探测这些射线,从而分析出金的含量。这种仪器除了必须符合正规实验室的精密能谱仪的标准外,还会遇到两个十分困难的条件,第一,它必须能经受得住矿山恶劣的野外环境,包括高温、高湿度、高粉尘和剧烈的碰撞。第二,它必须十分轻便,能够由一个操作员很容易带到野外并且不减少他在周围活动和工作的能力。 An even more portable source of X-ray fluorescence has been developed that can detect and quantify trace amounts of gold on the work surface. The technique is to use the 88Kevγ rays emitted by Cd to excite KβX-rays of gold and probe these rays with instruments to analyze the gold content. In addition to meeting the standards of a regular lab’s precision spectrometer, the instrument encounters two very difficult conditions: first, it must survive the harsh field conditions of the mine including high temperature, high humidity, High dust and violent collision. Second, it must be very light and can be easily carried by an operator to the wild without diminishing his ability to move around and work.
