Article Synopsis
- Pu-244 is the longest-lived and least studied isotope of plutonium, primarily produced through nuclear detonations, with a wide range of plutonium atom ratios found in environmental samples.
- The study evaluates the effectiveness of a 1 MV Accelerator Mass Spectrometry system in Seville for analyzing low environmental levels of plutonium, highlighting challenges posed by trace thorium in samples.
- Results demonstrate a specific background detection level for plutonium and validate the method through analysis of reference sediments from the International Atomic Energy Agency, complemented by discussions on isotopic abundances of various plutonium and uranium isotopes.
New data on the presence of I in seawater in the Southern Hemisphere measured by Accelerator Mass Spectrometry (AMS) is presented. The samples were collected in 2014 along the Namibian coast during a cruise organised by the National Marine Information and Research Centre (NatMIRC), the national laboratories of the Ministry of Fisheries and Marine Resources (MFMR) in Namibia, and the IAEA Environment Laboratories (IAEA NAEL) in Monaco. The Benguela upwelling system is known as one of the most important marine upwelling regions in the world.
