This method specifies the minimum requirements and laboratory methods for the analysis of 210Pb with alpha-spectrometry in sediment samples.
Samples are collected using crab sampler or gravity sampler, sealed on board and finally kept at -18°C. Post processing will take place in the land laboratory by freeze-dry. 210Pb is determined through its grandparent 210Po. Isotope decay correction is applied if the duration between sampling and measurement introduce discernible variation in 210Pb activity.
