This Task Group to deal with radioecology of rice has been launched at the 3rd International Conference on contaminants in soil Environments in Australiasian-Pacific Regions that was organized in Beijing, in November 2003. It is co-chaired by Shigeo Uchida from NIRS (Japan) and Hirofumi Tsukada from IES (Japan), with initial members from China, Korea and Japan.
The objectives are to collect transfer parameters in the paddy field ecosystems, to compare the parameters obtained in different regions and countries, to structure a database on behaviours of radionuclides in these ecosystems, and finally to develop a transfer model for predicting the behaviour of the nuclides in the systems.
The Task Group follows up previous collaboration of IUR with FAO and IAEA on similar issues, especially on tropical and sub-tropical environments, and will be conducted in close relationship with the IAEA/IUR TG dedicated to Radioecological Parameter Values - Update of TRS 364 (TG led by P. Santucci and G. Voigt).
