Effect of Thermal Treatment of Building Materials on Natural Radionuclides Effective Specific Activity

Abstract

The influence of heat treatment (burning) of building materials on the effective specific activity of natural radionuclides was investigated. Analysis and processing of the obtained results allowed to obtain a consistent pattern of this process for each material. It has been established that the effective specific activity of natural radionuclides decreases along with growth of temperature of building rocks treatment. The results showed that it is possible to reduce the effective specific activity of natural radionuclides managing technological production modes and, consequently, to reduce the radiation doses of the population from these materials.

The Raw Building Materials’ Research Quantitative Characteristics Radioactivity in Volgograd Region

“…At the same time, the vectors, similar in the original multidimensional space, appear alongside and on maps. In order to reflect the relative value of one or another component of the vector, the corresponding parts of the map are colored in a specific color depending on the chosen color scheme [12,20]. As a result of the algorithm, the following maps were obtained (see Figure 1 and 2): • neuron inputs map: Raw, 40 K, 226 Ra and 232 Th; • special cards: Aeff, Distance Matrix, Quantization Error Matrix and Clusters.…”

“…It should be noted that all materials studied correspond to class I materials on radioactivity and can be used for the production of building materials and for all types of construction without restriction [8,12,21].…”

“…These include: 40 K, 226 Ra, 232 Th. The software allows to determine the specific activity of natural radionuclides (NRN) and on the basis of the obtained results to calculate their effective specific activity using the formula [12]:…”

Digital technologies for searching and processing unstructured Information in modern higher education

“…The model presented in this way is one-dimensional, but for searching and processing documented information, pseudo-multidimensional HMMs are of interest, consisting of a finite number of elements, called superpositions, each of which in turn is a separate HMM [15].…”
