Chapter 6: Radionuclide Transfer Factor from Forest Trees and Other Plant Species to Food

Transfer factor (TF) is a parameter that has been investigated for a long time and has recently undergone several modifications. It depends on other factors; therefore, it is best to use its specific values for studies of specific forest ecosystems. Usually, TF is applicable for calculating the distribution of radionuclides in an ecosystem and for calculating the dose rate for parts of an ecosystem and for humans. There are a number of reference values which can be used or with which individual measurement values can be compared. In this work, some relevant TF values are presented for forest ecosystems, with particular attention given to edible species in temperate forests.
