Abstract
The article presents the results of work with the hardware and methodological complex for elemental analysis. The nickel content in the sample is determined based on the PGNAA method. This method of substance analysis is based on the measurement of radiation generated as a result of nuclear reactions when a sample is irradiated with a neutron flux. This method is an effective means of obtaining information about the elemental composition of geological objects, allowing to identify and determine the content of the studied elements in the composition of the sample. The technique is based on the registration of secondary gamma radiation of the sample arising in the reactions of radiation capture of thermalized neutrons. As a gamma detector in this work, a scintillation detector based on a LaBr3(Ce) crystal is used, as an ING-07T fast neutron generator. The spectrum under study is the difference between the background spectrum and the sample. The sample is presented in the form of a powder or in the form of a solid cylindrical block measuring ∅10×4.5 cm and weighing 300 g. The elemental composition of the sample is determined based on the dependencies of the area of the peaks of total absorption on the spectrum on the mass of the element. To do this, it is necessary to conduct experiments on irradiation of samples with different concentrations of the element under the same conditions. Next, the area under the peak of the element is measured and the dependence on the mass is constructed. Based on the obtained dependence, the mass of nickel in the test samples was calculated. The estimated mass values coincide with the specified ones within the error limits. The minimally determined mass concentration of nickel at this installation was estimated, which turned out to be 0,35 ± 0,11 %, which is in good agreement with the values in similar studies.
