Abstract  

A method is described for the non-destructive determination of210Pb and226Ra in sediments. The procedure is based on the direct counting of the 46.5-keV -ray of210Pb and the 351.9-keV -emission of214Pb. The self-absorption of the 46.5-KeV -ray is corrected using a technique involving direct gamma transmission measurements on sample and efficiency calibration standard. Several reference materials when assayed by the described method yielded results in general agreement with the certified values. The application of the method is illustrated through the analysis of the excess210Pb profile of a Lake Ontario sediment core.
