抄録

A giant earthquake (East Japan major earthquake) of M9 struck East Japan at 14:46 on March 11, 2011. Subsequently, tsunami attacked Fukushima Daiichi Power Plant, where all AC power supply fell into loss state. As a result, in all of 1-3 Nuclear reactors, meltdown befell. Then, significant amounts of radioactive material have been released into environment. The purpose of this study is to search environmental factors such as weather condition that may effect on air dose rate of radiation in each spot across eastern Japan. The data we dealt with are "the spot-specific air dose rates of radiation those were observed at 36 spots in eastern Japan", which were published in the morning edition of Asahi Shimbun from 13 April 2011 to 13 August 2011. Using a non-linear regression model based on a composite half-life model for radio-activities, we analyzed the data.
