Few experiments that deal with uptake of technetium in marine fishes have been reported, lire plaice Pleuronectesplatessa showed an equilibrium concentration factor of around 9 after 61 days, when - " Tc04 was added to seawater. The highest eoncen-trations were attained by kidney and the lowest by muscle. A mean biological half-life of 46 days was observed [92], The thornback ray Raja clavata attained equilibrium coneenlration faetors near 8. The distributions of Tc at the organ/tissue level in these two species of fish were remarkably similar for both the direct water uptake and the labeled food experiments. The data may be compared with the concentration fac-...
