AbstractAbstract
[en] Characteristics of radiation apparatus, sources and detectors, now in serial production, designed for X-ray diffraction logging in boreholes and mines, as well as for the analysis of samples and specimens, are given. Methods of selecting a standard-natural-background region in the secondary gamma-ray spectrum are discussed. The results of experimental investigations into the selection of an optimum standard-natural-background region for tungsten, antimony and copper ores are reported; examples of practical application of the procedure proposed in well logging and mine sampling are given. As a rule the relative error of X-ray diffraction sampling does not exceed 10 to 20 per cent
