| 中文摘要: |
| 目的 研究电感偶合等离子质谱仪 (ICP-MS)测量技术在核事故应急监测中的应用,提高核事故后食物和水中放射性污染检测技术水平.方法 采用微波消化、标准参考物质质控、内标法测量等方法.结果 几种标准参考物质的测定值与刻度值比值在 95 %～10 9%之间,食物和水样测定结果近似于其他报告结果.结论 由于ICP-MS在测量重元素时结果较好,在核事故应急监测中的应用尚需要进行进一步研究. |

| Objective To study the application of ICP-MS technique to radionuclides analysis,and improvement of monitoring techniques in nuclear accidents. Methods Microwave digestion was used in sample treatment.Standard reference materials were used for quality control.The internal standard method (103Rh) was used in the quantitative analysis. Results The analytical results of several stable elements and two radionuclides were in good agreement with the certified values 95%～109% and their concentrations in food and water samples were similar to those in other reports. Conclusion ICP-MS technique is effective in measurement of heavier radionuclides.Considering the sufficient sensitivity and the rapidity and simplicity of the measurement,further research are expected for the analyses of radionuclides in nuclear accidents. |
