FIELD: X-ray radiometric analysis.
SUBSTANCE: sample is irradiated with gamma- or x-rays with the energy below the K-edge of the tested sample's absorption right after irradiating the sample with gamma- or x-rays with the energy above the K-edge of the tested sample's absorption. The amount of radiation below the K-edge of absorption dispersed by the sample is measured, and the concentration of the analysed element is defined through the remainder of the sum of ratios of characteristic radiation of the sample's analysed element to the streams of dispersed radiation with energies above and below the said K-edge of absorption, and the value which is proportional to the sum of ratios of the characteristic radiation stream of the sample's analysed element to the streams of dispersed radiation with energies above and below the said K-edge of absorption.
EFFECT: improved analysis accuracy in complex chemical compounds.
