Abstract:
Uptake HTO from seawater by five kinds seashell and formative dynamics of bound tritium in organ of seashell are studied by using the isotope-tracer techniques in order to get a better understanding of the marine environmental behavior of HTO. The results show that the tritium in seashell exists in free water tritium and bound tritium form. The free water tritium is main form; its content observed was more than 97.4% of total tritium. The bound tritium content was very lower, only being 0.4% - 2.6% in total tritium. The speed of HTO untaken by seashell is very rapid, specific activity of HTO in three kinds seashell had reached their maximum only 2 h after treatment. The bound tritium in seashell increases slowly with time. The results of analysis of concentration factor (CF) values indicate that HTO would not concentrate in the seashell.
