Review and analysis of the main methods for determining the activity rate of tectonic faults based on the results of radonometry

The work compares various radiometry methods for accurately mapping fault zones in complex and simple mining and geological conditions. It also examines the conditions required for their application to confidently evaluate the degree of geodynamic activity of the identified tectonic fault zones, including minimizing negative impacts during the construction of various facilities, including linear transport and energy infrastructure. The authors analysed various materials on previously conducted research on this topic to compare approaches to the problem and develop numerical dependencies. In addition, it was evaluated the dependencies obtained by many researchers and their advantages and disadvantages. After thoroughly analysing previously developed methods and numerical dependencies for determining the degree of activity of tectonic faults, the most preferable method was selected from the list based on several criteria. The applicability parameters of the previously proposed numerical scale of fault activity based on radonometry data were clarified. The numerical scale itself was significantly improved. Based on the analysis of existing radonometry methods, the most acceptable method and an improved universal scale for determining the activity of tectonic faults, which is quite suitable for practical purposes, were proposed. The developed universal numerical scale still has no analogies. Radonometry in its various forms can be used to reliably evaluate the degree of geodynamic activity of the identified tectonic fault zones. For this purpose, the corresponding methodology and numerical scale were chosen.
