| 内容記述 | Surface soil samples collected in the Jiuquan region in the downwind area of the Chinese nuclear test site (CNTs) in northwestern China were analyzed for Pu isotopes. The 239+240Pu activities ranged from 0.025 to 0.892 mBq g-1, varying significantly with different sampling sites. The Dunhuang city which located in the southwestern part of the Jiuquan region received the heaviest Pu deposition. The 240Pu/239Pu atom ratios were 0.080-0.193 with an average of 0.167, slightly lower than the global fallout value. The results further convinced the influence of the CNTs for the Pu contamination in the Jiuquan region. | |||||
