COGEMA-La Hague nuclear reprocessing plant in the Cotentin Peninsula (northwest France) releases in the atmosphere about 19 TBq.yr-1 of radiocarbon. Three experiments in a terrestrial environment with sampling of a bio-indicator like furze were performed in 1997, 1998, and 1999, and additional air samples in the chimney plume were measured. Results presented here establish the 14C distribution in the La Hague environment and suggest that a part of the 14C content in the vegetation near the coast results from a 14CO2 degassing of seawater supplied with the liquid waste from the nuclear plant.
