Activités de 238Pu et de 239+240Pu dans les sols cultivés de la basse vallée du Rhone.

Duffa, C.; Renaud, Ph.; Calmet, D. Comptes Rendus de l'Académie des Sciences. Série 2a, Sciences de la Terre et des Planètes, no.4t.332 p. 275-281

Summary

Measured 238Pu and 239+240Pu activities in French soils can be explained by the fallout from atmospheric nuclear tests and the disintegration of a US nuclear reactor satellite in 1964. However, some soil samples from the lower Rhone valley show higher mass activities, due to the Marcoule nuclear fuel reprocessing plant discharges. Soil samples from the Camargue, flooded in 1993 and 1994, where Rhone River sediments have been deposited, contain Pu from liquid effluents released by the nuclear plant. Seven samples taken near the nuclear facility show a direct influence by its atmospheric releases. Samples from soils irrigated with Rhone River water for 30 years do not show any activity significantly higher than regional means.
