摘要: Naturally occurring 210 Pb and Po are important tracers used in marine environment studies. In this study, measurements samples (sediment, sea water biota) were performed using alpha spectrometry. Chemical recoveries obtained 209 tracer. Two different approaches for determinations also compared. First, to keep the original about 1 year eliminate excess reach Po- equilibrium before radiochemical separation of Po. The second is extract samples, then wait attaining Pb- solution obtain activities. time corrections originated from radioactive decay grand parent discussed.
