Des elements radioactifs des familles de l'Uranium 238 et du Thorium 232 ont ete recherches dans des echantillons de Parmelia suicata et de Xanthoria parietina provenant de biotopes differents. Ces especes ont ete utilisees dans le suivi de la bio-accumulation de ces elements, emis par une centrale thermique fonctionnant au charbon, en Saone-et-Loire. Les concentrations, naturelles ou anthropiques, de la plupart de ces radioelements dans les lichens diminuent selon le site de la facon suivante: decharge radifere zone fortement uranifere zone industrielle zone rurale. Le caractere problematique de certains de ces elements est souligne et un tableau de resultats obtenus sur des echantillons de differentes especes d'une station a sol uranifere est propose a titre de reference.
