摘要

建立以大容量微波干燥碳化灰化一体装置为载体制备生物灰样、采用高纯锗γ能谱法直接测量生物灰样放射性核素的生物样品分析测定方法，实现核电厂周边环境生物样品中γ放射性核素活度浓度的快速测定。与传统灰样制备法对比研究结果表明：该微波灰样制备法可使生物样品制样效率提高约2~5倍，平行样相对偏差小于14.8%，加标回收率为87.0%~116%。采用配对,t,检验法验证，二者之间无显著性差异。该方法具有准确度高、分析效率高、操作简单、安全环保等优点，是快速测定生物样品中γ放射性核素活度浓度的理想方法。

Abstract

In this study, biological ash samples were prepared by establishing a high-capacity microwave integrated device for carbonizing and ashing. Radioactive nuclides in biologically derived ash samples using high-purity germanium gamma spectrometry were directly measured for rapid determination of γ radionuclide activity concentration in environmental bio-samples from nuclear power plant surroundings. A comparison with the traditional ash preparation method was also conducted. The results showed that the microwave-ash preparation method can improve the preparation efficiency of biological samples by approximately 2 to 5 times, with a relative deviation of less than 14.8% for parallel samples and a spike recovery rate ranging from 87.0% to 116%. A paired T-test revealsed no significant difference between the two methods. The proposed method has the advantages of high accuracy, high analytical efficiency, simple operation, greater security, and environmental friendliness. It is an ideal method for quickly determining γ radionuclide activity concentration in biological samples.
