摘要
Abstract
239 Pu in seawater was measured by accelerator mass spectrometry(AMS)system independently developed by China Institute of Atomic Energy.The 239 Pu in seawater samples was separated and purified by anion resin,and the target samples were prepared by ferric hydroxide co-precipitation method.A set of tap water samples was prepared as blank samples to evaluate the measurement method with a detection limit of 0.9 fg(2.0 μBq).By this method,239 Pu in seawater samples was measured and analyzed.And the uncertainty of the measurement method was analyzed.关键词
