Collaboration between botanists and soil scientists towards the examination of radiation exposure caused by the Fukushima Daiichi nuclear power station disaster on the environments of paddy fields and rice plants, and discussion of future measures for reductions

Research grant

Project Description

Soil scientists and botanists collaborate regarding the proliferation of radioactive material on the environment due to damage caused by the Fukushima Daiichi nuclear power station. (1) Selection of a rice plant variety that can be cultivated in soil with radioactive accumulation, inspection of rice paddy soil purification of rice plant varieties with high levels of radioactive material absorption capacity, and the collection of data by simultaneous measurement of soil and microorganisms for the recovery of rice paddy environments. (2) Progress with development of farming techniques using the general cultivation of rice plant varieties simultaneously, and collect and make available to the public data which contributes to the activities towards reducing radioactive material in the environment.

Research record
Up until now, Professor Mimura has done research on the transportation of ions in plant cells using algae and plant materials, and is continuing research on the absorption and distribution of ions within living organisms. The participation in this project was in response to the current environmental exposure to radiation in Fukushima Prefecture, and aims to use phytoremediation to make effective use of the the transportation of ions in plants.
