FEATURES OF USING TARGETS WITH PENETRATING RADIATION IN THE X-RAY RADIOMETRIC METHOD

Abstract

When analyzing and selecting elements using the X-ray radiometric method, characteristic beams obtained from targets are often used as a radioactive source of primary excitation in measuring instruments. The geometry of targets with reflected radiation currently used in measuring instrument sensors creates certain inconveniences, both in terms of their size and due to the creation of additional disturbing rays of the flashlight passing through the layer layer from the original one. source and directly includes the detector. These disadvantages become more obvious with X-ray radiometric logging. To avoid these shortcomings and inconveniences, we propose a new approach to the use of targets, the essence of which is to use not reflected, but secondary rays generated in the target and passing through it. In this case, the target is placed at right angles to the radiation trajectory of the primary source, as a result of which characteristic X-rays of the target appear, the energy of which is less than the energy of the k-edge of absorption of their material, pass through it unhindered and appear in the primary spectrum, representing themselves as their analytical line. The specified geometry of the installation is realized by simply replacing the protective layer of the radioactive beryllium isotope with a target in the probe.
