Burlington, Ont. : Environment Canada, National Water Research Institute, [1986] 16, [7] p. : charts NWRI contribution ; no. 86-69 Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographic references (p. 15-16). "A simple method is described for the radioisotopes determination of title in sediment for dating purposes. The technique involves direct counting of low-energy gammas emitted by the two radionuclides. A simple procedure is used to account for the self-absorption of gamma-rays in the sediments. The method gives very reliable methods when compared with prevailing techniques and using certified reference materials"--Management perspective.
