Abstract

In the biogeochemical cycling and food chain transfer the mobility and bioavailability of technetium are largely governed by its physico-chemical forms present in the environment. The assessment of the long-term behaviour of technetium is difficult mainly because technetium is a man-made element which has no stable isotopes. Moreover, 99-Tc, recently introduced into the environment, cannot be considered in complete equilibrium with the biosphere. In recent years much information has been obtained in experimental radioecology on the geobiochemical processes which determine the high mobility and the distribution of technetium in the various compartments of the biosphere and its transfer through food chains. The results now available from laboratory and field studies indicate that the transfer of technetium from the environment to man, considering also critical pathways, will not represent serious risks for human health.
