Air dose rates conducive to external effective dose assessment for farmers after Fukushima Daiich NPS accident in the economic core zone, Nakadori, of Fukushima, Japan.

Abstract

Japan Agricultural Cooperative Fukushima asked Japan' goverment and Fukushima prefecture to measure radiation dose rates per a field unit, but its petition was rejected. Therefore, getting the nationwide cooperation of consumers cooperatives, it has carried out soil pollution measurement of the tens of thousands fields, called Dojosuku, meaning pollution screening of soil.  Here I suggest the new technique that used the clearance dose-rate because there is not the evaluation of the exposure radiation dose of farmers in this.
