Abstract

The final qualifying work on the topic “Study of daily variations in the pore activity of radon in surface soils” contains 107 pages, 20 figures, 31 tables, 90 sources used, 1 an appendix.

Keywords: radon flux density, radon volume activity, soil radon dynamics, diurnal variations, detection of meteorological parameters.

The object of the study is the monitoring data of the ionizing radiation flux density in the city of Tomsk at the experimental site of the Tomsk Observatory of Radioactivity and Ionizing Radiation.

The purpose of the work is to study the dynamics of the radon flux density from the soil into the surface atmosphere and to search for influencing factors.

In the course of the study, a search was made for patterns in the behavior of soil radon on a daily, synoptic scale.

Because of the study, the factors influencing the dynamics of radon in the soil were identified, and databases were formed based on the results of measuring the volumetric activity of radon at different depths.

Degree of implementation: High. Scope: Geophysics, seismology.

Economic efficiency/significance of the work: High.

In the future, it is planned to continue research in this area: to replenish the databases and refine the parameters of the radon transport model in the geological environment.

Scientific novelty: The daily variation of radon pore activity at different depths in the ground has been investigated.

Practical significance: The possibility to study the daily variation of radon pore activity at different depths and with different detectors and radiometers.

Introduction

Field autonomous complex, being developed progress master's dissertations, For monitoring of pore activity of radon in surface soils maybe turn out to be useful at usage developed us autonomous field complex on stations involved in monitoring, in combined with appliances, designed to measure the pore activity of radon in soil surfaces, maybe raise authenticity received forecast data, a also to appear opportunity define and/or refine the parameters of the radon transport model in the geological environment and surface atmosphere.

The content of a large amount of radon in the zones faults found application in areas with elevated seismic activity, in the study of tectonic movements of plates. In 1966 in the city Tashkent, capital Uzbekistan in time earthquakes, managed fix, a sharp increase in the saturation of radon, concentrated in groundwater, 5-7 times in a few days before there was a push. On at the moment, such a principle of monitoring these physical processes used to track, fix and predict seismic activities in India, Israel, USA, Taiwan, Turkey and other countries. IN For the effective operation of this complex, Russia needs so that the installation satisfies a number of not unimportant features, such How, severe weather conditions in winter and spring period time. basisto create an autonomous field complex for density monitoring flow radon With terrestrial surfaces in Russia served high cost foreign analogues.

The purpose of this work - is to conduct a study of daily variations in the pore activity of radon in surface soils.
Tasks:

Overview and analysis literature by topics scientifically - research work.
Conduct an analysis of instruments and methods for measuring the volumetric activity of radon in the soil.
Execution calibration installations for definitions correction
