The use of the GIS Kriging technique to determine the spatial changes of natural radionuclide concentrations in soil and forest cover

摘要

BackgroundThe distribution of radionuclides occurring naturally in the earth depends on bedrock characteristics. Therefore, the spatial distribution of radionuclides is not uniform. Consequently, radionuclide information is vitally important in determining and monitoring the spatial variation of the radionuclide concentrations that are over the limits for the sustainable environment and human health.
