In usual working conditions, our strain will accumulate radioactive cobalt. Cobalt is toxic by inhalation and contact. It has been proven to cause cancer, respiratory system damage, skin damage among others on humans and various effects on other species including plants, <A href="#Cobalt1"> [1] </A>. It is important to notice that cobalt in our bacteria could be more concentrated than in usual resins. Radioactivity of the compound adds to the danger, with various damages that can’t be neglected : nausea, cerebral edema, sterility, foetal damage... Only low-dose effects can be effectively treated. A previous study <A href="#Cobalt2"> [2] </A> showed that cobalt accumulation capacity of the bacteria is not infinite and that bacteria death will conduce to the liberation of cobalt in the medium with the potential health issues that have been described if it ends up in the environment. For these reasons it is very important to ensure that the “Cobalt Buster” bio-filter will not release bacteria in environment after the processing. | In usual working conditions, our strain will accumulate radioactive cobalt.

Nous avons considéré la sécurité du publique et de l'environnement à la fois du point de vue du risque et de la probabilité. Afin de réaliser au combien les procédure des centrales nucléaires et le traitement des déchets de celles-ci sont strictement réglementés nous avons organisé deux visites. En premier, nous avons visité la centrale nucléaire du Tricastin afin d'avoir une idée de la façon dont sont confinés les composants radioactifs et comment les travailleurs sont protégés. Ensuite, nous avons choisis de visiter le site de Centraco qui est engagé dans le traitement des déchets faiblement et moyennement radioactifs.
