Abstract

The concentration of 99Tc was determined in archived time series seaweed samples collected at Klint (Denmark). The results demonstrate a significantly seasonal variation of 99Tc concentrations in Fucus
vesiculosus with maximum values in winter and minimum values in summer. The mechanism driving this seasonal cycle was explored. With the measured 99Tc concentration in seawater collected in the same location and date as for seaweed, the concentration factor of F. vesiculosus to 99Tc was investigated. Constant value of concentration factors of 99Tc independence of sampling date, with an average value of (1.9 0.5) 105 L/kg, were obtained. This indicates that F. vesiculosus can be used as a reliable bioindicator to monitor 99Tc concentration in seawater.
