Quantification of radionuclide transfer in terrestrial and freshwater environments.

The paper gives an overveiew of radioecological concepts, reference information on plants and soils used in the project. Main classification schemes applied to summarize the data on radionuclide transfer to plants are also described. Generic quantities and units used in the current document are also given. They are mainly defined according to the the ICRU 65 report. 1. DEFINITIONS, QUANTITIES AND UNITS In 1997, a report committee was initiated and established by the International Commission on Radiation Units and Measurements (ICRU) to prepare a report on statistical aspects and sampling strategies when measuring radionuclides in the environment.
