Abstract

Within the scope of a joint IPSN/EDF research program, it is possible to present a statement of the environment out of industrial influence for two areas, one in the Nogent-sur-Seine region, the other around Dampierre, where seasonal sampling was monitored over two years. In Dampierre, the same sampling was implemented within areas exposed to atmospheric releases of the nuclear plant in order to assess the facility impact. The matrices selected for this specific survey include perennial self-sown vegetation (ivy leaves, meadow grass, blackberries), caducous tree leaves (durmast-oak), honey, game, cultivated fruits (apple), pasture grass, milk and cattle meat. The available quantity of results evidences a discrete marking effect by the facilities both in radiocarbon and tritium, but does not allow proposing a modeling.
