| Abstract: | Experimental data on the transfer of long-lived radionuclides through food chains have been summarized from the available literature. The transfer to a given organism is characterized by a transfer factor (TF), defined as the activity in the organism relative to that in the ingested food or sediment. The TFs of Pu, Am and Tc from sediment to benthic species have been directly measured and generally do not exceed a value of 0·1. The TFs from prey to predator are related to uptake and retention parameters whose values can be derived from experimental data. It was estimated that these TFs do not generally exceed unity and that an increase of concentration through a food chain is very unlikely. |
