在专门的文献中,指出了(?)在金属石选别实践中的应用前景。X射线荧光法(PΦM)是X射线(?)种。在成功地用于大块矿石拣选和按矿块分选方面其它X射线辐射法的变种还有一种γ射线荧光法(M)。该法是以利用γ放射性同位素源来激发被分析元素固有的x射线为基础的。现在,主要注意力放在发展x射线荧光法上。此法与γ射线荧光法相比,在放射性安全和能利用X光管的阳极电流和电压的变化能在很宽的范围内调节初级和射线强度等方面都具有明显的优越性。
In the special literature, we point out the application of (?) In metal stone sorting practice. X-ray fluorescence (PΦM) is the X-ray species. There are also gamma-ray fluorescence methods (M) for variants of other X-ray methods that have been successfully used for bulk ore sorting and sorting for nuggets. This method is based on the use of a gamma radioactive isotope source to excite the x-rays inherent in the element being analyzed. Now, the main focus is on x-ray fluorescence. Compared with γ-ray fluorescence method, this method has obvious advantages in terms of radioactive safety and ability to utilize the change of anode current and voltage of X-ray tube in a wide range to adjust primary and radiation intensity.
