摘要
Samples from sediment cores, collected from a site close to the Sellafield outfall and dated using conventional gamma- and alpha-spectrometry, have been analysed using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Thermal Ionisation Mass Spectrometry (TIMS). This has provided information on the isotopic composition of plutonium in the liquid discharges from Sellafield; such information is not available using conventional cc-spectrometry alone. There was very good agreement between the Pu-240/Pu-239 ratios obtained by the two MS methods. More recent discharges have been characterised by a progressive decrease in the relative proportion of Pu-239.
