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.
