| Abstract: | Measurements of210Pb at various dephts in a sediment core from the Santa Cruz Basin off the coast of California have been made. The radiochemical separation of210Pb was carried out after ashing the sediment at 400 °C. The activities of the purified210Pb was assayed in a low background beta counter by counting the 1.17 MeV betas of its daughter product210Bi. The method for the chemical separation of210Pb and the results are discussed in the paper. |
