Les poussières du Sahara qui remontent en Europe sont-elles radioactives du fait des essais nucléaires des années 1960 ? La signature isotopique des poussières sahariennes de mars 2022 correspond plutôt aux essais nucléaires réalisés par l’Union soviétique et par les États-Unis pendant les années 1950 et 1960.
