METHOD FOR DETERMINING AND PREDICTING THE VOLUME OF RADIOACTIVE SOIL Russian patent published in 2022 - IPC G01T1/169 

FIELD: sensing technology.

SUBSTANCE: invention can be used to determine and predict the volume of soil exposed to radioactive contamination. Essence: the boundaries of the radioactively contaminated territory are defined. Triangulation models of the upper and lower surfaces bounding the desired volume are constructed. A three-dimensional model of the desired volume is built and this volume is calculated. At the same time, a triangulation model of the surface relief of a radioactively contaminated territory constructed using data from an electronic vector map of a geoinformation system is used as the upper bounding surface. To construct a triangulation model of the lower bounding surface, a network of sensors for measuring soil and air temperature, soil and air humidity, capillary pressure in the soil, dose rate on the soil surface is installed. Soil samples are taken at the sensor installation sites for subsequent morphological, radiometric and spectrometric analysis. Based on the results of measurements and analysis of soil samples, the rates and depths of penetration of technogenic radionuclides into the soil are determined using impurity transfer models. Certain penetration depths of radionuclides into the ground are used to construct a triangulation model of the lower bounding surface. Based on certain rates and depths of penetration of radionuclides into the soil, the volume of radioactive soil is predicted for specified time periods. The priority areas for carrying out restoration measures for the greatest depths and rates of penetration of radionuclides into the ground are determined.

EFFECT: improving the accuracy of determining and predicting the volumes of radioactive soil at various points in time.
