| Radionuclide Distribution in Sediments and Sedimentary Rates in the Jiaozhou Bay |
| Rdionuclides in sediments of the Jiaozhou Bay and its surrounding area were measured using the HPGe γ spectrum method.238U,228Ra,228Th,226Ra,210Pb,40K and 137Cs were detected in sediment samples.The results show that the radionuclide contents of the sediments collected from the east bay are relatively high.The vertical distribution of nuclides in the sediment cores was analyzed,and the sedimentary rates were evaluated by 210Pbex and 137Cs methods,yielding the value of 0.64～1.74 cm/a. |
