摘要
采用激光荧光法对“5·12”地震后某工号建筑垃圾和土壤样品进行了铀的测定。方法检出下限D．L≤3×10^-1g／mL，相对标准偏差RSD为7．4％，回收率达到86％-109％。对实验数据进行了分析和初步评价，结果表明，该工号所测样品铀含量基本处于天然本底水平。
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.
