Description
Radionuclides concentration by giant clams is associated with feeding habit. It's also a main food for polynesian atolls inhabitants, elsewhere than Mururoa island because this mollusc is not consumed like all the other fishery products from this atoll lagoon. Nevertheless measurements of ten artificial radionuclides are performed in edible parts of giant clams fished from Mururoa lagoon since the beginning of nuclear tests. The decay of radionuclides concentration is described versus time. To go further on we have computed the dose-equivalent for internal exposure of an eventual giant clams eater. It is estimated that the resulting risk of malignancy is below than 1 per 10 000
Abstract (French)
Du fait de ses modalites nutritionnelles, le Benitier concentre energiquement la plupart des radionucleides. Bien qu'il ne soit pas consomme a Mururoa, de meme que tous les produits de peche provenant du lagon, il est apparu interessant d'etudier ce mollusque, car il tient une place importante dans le regime alimentaire des habitants des atolls polynesiens. Dix radionucleides artificiels ont ete mesures dans les parties comestibles des Benitiers recoltes depuis le debut des essais nucleaires a Mururoa. La decroissance de leur radioactivite massique en fonction du temps est decrite. Elle permet de calculer les equivalents de dose d'exposition interne auxquels auraient ete soumis des individus qui les auraient consommes. L'enveloppe maximale du risque qui en serait resulte est estimee inferieure a 1 pour 10 000 pour les affections malignesAdditional details
