Plutonium isotopy as a dating tool to reconstruct the recent history of land use in South America

A French-South American consortium led by the LSCE (CEA-CNRS-UVSQ) is working to explain the chronology and spatial distribution of radionuclides deposited in South America following atmospheric nuclear testing. Their research, based on measurements of plutonium isotopes in soil and sediment samples, will enable the precise reconstruction of the evolution in land use since the 1960s.
