| Abstract: |
| The concentration of dissolved uranium and the relative abundance of two uranium isotopes, U234 and U238, in water samples from the Jiu Longjiang River and, the Xiamen Bay, Fujian province, have been determined and, by use of these parameters, the relative volume proportions of mixed water have been calculated in this paper. Ten surface water samples collected from two water sources in the studied area during May, 1981 are analyzed by using alphaspectrometrie method Jiu Longjiang River water itself contains an average of about 0.24μg/1 U with active ratio of 1.22. Eight samples from surface water mixture varied from 1.20 to 2.60μg/1 with A. R. from 1.09 to 1.14. Analytical data show that the river-sea system provides excellent test on the mixing equations of two components. According to this mixing model, three water association sectors have been divided on the basis of the distribution of uranium and isotopic data. These initial data, although limited, provide an interesting insight into future potential research |
