Experience in the introduction of X-ray fluorescence express-analysis at the KhrustalRnensky ore concentration plant

An experiment on introduction of a roentgenoradiometric fluorescent method at the Khrustal'nensky ore concentration complex is described. All types of rapid analysis are carried out by the roentgenoradiometric method using the spectral ratio technique, which ensures a weak dependence of the results on the source decay, the detector efficiency, etc. 241Am was chosen as the primary radiation detector. Intermediate radiation sources,i.e. targets of Eu and Sm oxides were chosen to improve the sensitivity. Due to the introduction of the above analysis technique the cost of testing and the time of obtaining the results have reduced
