Direct determination of geochronologically-useful radionuclides in sediments by low-energy photon analysis / S.R. Joshi and A. Mudroch. : En13-5/86-183E-PDF
"The levels of Pb-210 and Am-241 in sediments are normally measured by using complex chemical procedures which are both time consuming and require considerable dexterity in separation chemistry. The two radionuclides, however, also emit very low energy gamma rays which can be measured on a properly calibrated hyperpure germanium detector. The present paper describes the development of such a qamma-ray spectrometric technique. The technique is applied to assign dates to two sediment cores from the Great Slave Lake, NWT. The results are compatible with the dates derived from Cs-137 measurements"--Management perspective.
