我国环境土壤和地表水沉积物中Pu的分布特征研究
Concentration and Characterization of Plutonium in Soils and Groundwater Sediments in China
摘要
Abstract
The activity of 239+240Pu in surface soils from different areas of China varies,but typically less than 1 mBq/g.It was indicated by previous study that no influence from Chinese Nuclear Test Site (CNTS) has occurred to the upwind areas.However,the Pu inventory at one point in downwind areas of CNTS is five times higher than that of global fallout and 240Pu/239Pu atom ratio in one lake sediment is below 0.18,which were suggested to be the influence of CNTS.Further field investigations in detail are necessary to master the total figure of CNTS.For the areas far away from CNTS,Pu inventory and 240Pu/239Pu atom ratio are both similar with global fallout.The forms of Pu vertical distribution vary for different soils,depending upon various factors (e.g.soil type,weather condition).关键词
