Radiological impact of releases of radionuclides into the environment should be evaluated with the aid of mathematical models with proper radionuclide transfer parameters in the environment needed to be assessed. However, this is not always practicable, and thus there is reliance on data obtained from the literature. For many years the IAEA has been very active to collect and evaluate data on radionuclide transfer through food chain in the environment to humans. They published collections relevant to the transfer in the environment, which is regarded as international reference values. The present paper describes radionuclide transfer parameters, with special emphasis on three transfer parameters, transfer factor from soil to plant, transfer parameters from feed to animal products, and concentration factor from water to aquatic biota. Main part of the information comes from the publication of the IAEA. For each of these parameters, definition of the parameter, geometric average and maximum and minimum of reported parameter values, and the modifying factors to parameter values are elaborated. The TEPCO Fukushima Dai-ichi Nuclear Power Plant Disaster resulted in a local environmental contamination of radionuclide. It is needed that information relevant to radionuclide transfer in our environment should be abstracted from the environment as much as possible.
