Etude de la décontamination d'Arenicola marina (annélide,polychète) après contamination expérimentale par le caesium 137 ou le cobalt 60

From a nuclear protection standpoint, problems of decontamination are of great interest. In Arenicola marina L. a comparative study has been made on the elimination of two radionuclides, the metabolic functions of which are very different: ¹³⁷Cs and ⁶⁰Co. After experimental contamination with ¹³⁷Cs, significant decontamination is possible; however, elimination of ¹³⁷Cs accumulated in muscles is very slow. The elimination of ⁶⁰Co is very slow; its biological half-life in A. marina is about 3 months.
