Abstract: The uptake and distribution of stable 133Cs and 88Sr in sunflower (Helianthus annuus L.) were studied by pot experiments. The results showed that the content of 133Cs or 88Sr in leaf increased with the increasing soil concentration of each element. The 88Sr content in sunflower leaf was generally one order of magnitude higher than that of 133Cs in each same treatment level. The 133Cs and 88Sr were unevenly distributed in the different organs. The 133Cs concentration was higher in roots than in other plant organs (stems, leaves, flowers). Contrary to the distribution of 133Cs in plant, 88Sr, except for roots, were mainly translocated to leaves. The distribution of cesium and strontium are agreed with the results of present research on radioactive 137Cs and 90Sr, 133Cs and 88Sr could be useful to understand and predict the long-term movements of 137Cs and 90Sr, respectively. Sunflower is the acceptable plants for phytoremediation to the low-level radioactive soil.

Key words: 133Cs, 88Sr, Helianthus annuus L., uptake, distribution, phytoremediation
