摘要：

This paper gives the first data on Pu-239 Pu-240 and Am-241 in Chinese soils. Surface soil samples with a set of 0-5 cm and 5-20 cm depth were collected from Beijing, Taiyuan, Shijiazhuang and Jinang of China in 1990, and Pu-239, Pu-240, Am-241 and Cs-137, including naturally occurring radionuclides, in these samples were measured to evaluate their present levels and distributions. From these results, the average accumulated depositions were estimated roughly to be 24 +/- 13 MBq/km2 for Pu-239, Pu-240, 10 +/- 5 MBq/km2 for Am-241 and 1.2 +/- 0.7 GBq/km2 for Cs-137. The activity ratios of Pu-239, Pu-240/Cs-137 and Am-241/Pu-239, Pu-240 ranged from 0.016 to 0.026 with a mean value of 0.020 +/- 0.004 and 0.35 to 0.49 with a mean value of 0.43 +/- 0.05, respectively.
