A study on the elimination of 137Cs in mussels under contaminated fields and laboratory conditions

The natural depuration or bioelimination of ^l37Cs was investigated in Mytilus galloprovincialis under contaminated field and laboratory conditions. The depuration result represented by a single component and biological half‐life was found to be 63 days under Chernobyl condition during 1986–1987. On the other hand, the biological half‐life of ¹³⁷Cs were found in the range 19.7–27.1 days in the laboratory experiment. The bioelimination process was also found biphasic and dependent of temperature at 5°C and 13°C under laboratory conditions. The results obtained in the contaminated field and the laboratory are not comparable in the mussels.
