Pittauerova, Daniela; Tims, Stephen; Froehlich (previously Srncik), Michaela; Fifield, L Keith; Wallner, Anton; McNeil, Steven; Fischer, Helmut W.


Unusually high concentrations of americium and plutonium have been observed in a sediment core collected from the eastern Lombok Basin between Sumba and Sumbawa Islands in the Indonesian Archipelago. Gamma spectrometry and accelerator mass spectrometry data together with radiometric dating of the core provide a high-resolution record of ongoing deposition of anthropogenic radionuclides. A plutonium signature characteristic of the Pacific Proving Grounds (PPG) dominates in the first two decades...[Show more]
