| 英文摘要 | Both soil and plant samples of nine different plant species grown in soils from southeastern China contaminated with uranium mine tailings were analyzed for the plant uptake and translocation of U-238, Ra-226 and Th-232. Substantial differences were observed in the soil-plant transfer factor (TF) among these radionuclides and plant species. Lupine (Lupinus albus) exhibited the highest uptake of U-238 (TF value of 3.7 x 10(-2)), while Chinese mustard (Brassica chinensis) had the least (0.5 x 10(-2)). However, in the case of Ra-226 and Th-232, the highest TFs were observed for white clover (Trifolium pratense) (3.4 x 10(-2)) and ryegrass (Lolium perenne) (2.1 x 10(-3)), respectively. Th-232 in the tailings/soil mixture was less available for plant uptake than Ra-226 or U-238 and this was especially evident for Chinese mustard and corn (Zea mays). The root/shoot (R/S) ratios obtained for different plants and radionuclides shown that Indian mustard had the smallest R/S ratios for both Ra-226 (5.3 +/- 1.2) and Th-212 (5.3 +/- 1.7), while the smallest R/S ratio for U-238 was observed in clover (2.8 +/- 0.9).
