“…In this range, it is possible to obtain a good agreement between the data of the aerodynamic survey of γ-radiation after processing with the measured values from the results of ground monitoring. Comparisons made on field data obtained from agricultural fields in the Leningrad region (Russian Federation) confirmed this [54][55][56][57][58][59][60][61]. This shows the prospects of the method proposed by us for continuous monitoring of the radiation situation in agricultural fields.…”

The problems that arise in the surface layer of the soil during periodic emissions at nuclear power plants are considered. The necessity of constant monitoring of this soil layer at different times of the year is substantiated. Various methods of this control are considered. It has been established that it is extremely difficult to implement them in remote areas. A method has been developed for monitoring the surface layer of the soil using aerodynamic survey of the distribution of γ-radiation on the soil surface. This is extremely important during the preparation of agricultural fields for sowing crops in the spring. A new algorithm for restoring images obtained using aerodynamic imaging of γ-radiation is proposed. The results of a new algorithm for image processing and identification are presented.

“…The world has increased the pace of search for some strategies that can compensate for the use of fuel and reduce the level of pollution crisis [1]. Alternatives such as heat recovery [2,3], energy management [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] and renewable energy sources [6][7][8] have emerged in order to reduce energy costs, as well as solve environmental problems. The use of renewable energy technologies, such as solar, wind, geothermal, fuel cells etc., since clean energy production has increased significantly in many countries.…”

The presented article provides a comparative analysis of the methods of manufacturing technology for semiconductor branches of p- and n-type conductivity. For comparative analysis, a method is considered for obtaining ternary alloys based on the Bi2Te3 base material by pressing and zone melting. The sequence of the manufacturing process, the principles of operation and design of devices used to obtain alloyed substances, as well as methods for studying and measuring the electrophysical parameters of the thermoelement legs included in the assembled thermopile are described. The principles of automatic temperature control of an electric furnace by a two-position method are indicated. The advantages of the zone melting method are determined and the best values of the figure of merit of a thermoelectric material are shown. It is proved that the original values of the parameters of the branches are preserved after they are assembled into a battery.

One of the most promising forms of energy production for at least several decades is thermoelectric power energy, which converts heat directly into electricity. In comparison with other methods of extraction of energy, Tthermoelectric power energy has such distinctive features as compactness, low weight, noiselessness in operation, high reliability, does not affect the growth of greenhouse gases and an increase in the radiation background. It can be recognized that low current conversion efficiency and high cost are some of the disadvantages. But there is a huge plus, because TEPG does not contribute to the depletion of natural resources and environmental pollution, such as climate warming, which has caused concern recently. In this paper, we report on some technological features of methods for obtaining semiconductor materials for thermoelectricity and their properties.
