Geostatistical Modelling for 134Cs Released from The Fukushima Radioactive Fallout

Abstract

The distribution of radionuclides show variability as spatially. For this reason, determining the spatial distribution is very important. In the study, spatial analysis technique using as Point Cumulative Semivariogram (PCSV) method is modelled for the radioactive fallout which had occurred after the Fukushima Dai-Ichi Nuclear Power Plant accident. The theoretical basis of the Point Cumulative Semivariogram (PCSV) method is based to variogram analysis. PCSV allow the regionalized behavior of variables into use. PCSV modelling is applied for ¹³⁴Cs radionuclide in soil samples in the accident area. 5 different models are obtained to determine the transport properties and distribution of ¹³⁴Cs.
