| description | The radioisotope pollution shows two types of patterns: dry and wet deposits for nuclear power plant accidents. Two surface
pollution patterns were analysed by fractal. In Fukushima nuclear power plant accident, surface pollution by wet deposits was
estimated to occur. However, actually it was no rain and white crystals were observed on the surface. Then, fractal analysis was
carried out for the spatial distribution patterns of radio isotopes on the surface to judge the types of deposits. As a reference,
Chernobyl nuclear power plant accident was checked for the spatial distribution patterns of radioisotopes on the surface. The
objective patterns by fractal analysis were the surface pollution maps in Fukushima and Chernobyl, Abukuma river watershed map,
and NOAA/AVHRR. The calculation of fractal dimensions was carried out with the box counting for binarized images. Fractal
analysis results suggested the next conclusions. The radioisotope pollution in Fukushima might occur in both dry and wet deposits.
The dry deposit might make the pollution pattern similar to the watershed, while the wet deposit might make the pollution pattern
similar to cloud images. Moreover, most radioisotope contaminants might flow on the road in the forest valley and deposit on forest
with and without rainfall in Fukushima. |
