Development of Agricultural Tractors with Shielded Cabin for Decontamination

Abstract

Agricultural tractors with a shielded cabin were developed for decontaminating paddy fields that have been contaminated with radioactive material. The developed machines reduced the radiation dose rate of the interior of the cabin by approximately 50% or less from outside. Moreover, the dust concentration was reduced by more than 95%. The performances of the machines and the effect of the removal of surface soil were estimated via a decontamination test in Iitate, Fukushima.
