| 520 | |a"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. |
