| Abstract: | Uranium in building trash and soil samples from ＂May 12＂ earthquake area were determined using laser fluorescence spectrophotometry. The detection limit, relative standard deviation （RSD） and recovery rate were 3×10^-1g/mL, 7.4% and 86% - 109% respectively. The experimental data were analyzed and evaluated initially. The results showed that the uranium content of this location was at the normal level of background. |
