Abstract

Over one year has passed since Fukushima Daiichi Nuclear Power Station. Spatial and temporal changes in dose rate are measured several times in different spatial scales. Radio activity contamination map in a scale of small watershed by walking survey with gamma-ray spectrometer and GPS. Characteristics in spatila and temporal changes in dose rate are discussed in the paper.
