水样品和食品样品中210Po的研究进展

Research progress on the ^(210)Po of water and foodstuff samples

钋(Po)是一种非常稀少但是放射性很强的元素,^(210)Po是铀系α放射性核素中的一种,也是氡衰变相对较长的放射性核素产物之一,其毒性极高。^(210)Po可通过饮水和食物链途径进入人体,对人体造成的内照射是公众照射的重要组成部分。先进的^(210)Po测量方法在保障公众健康安全方面和辐射防护方面提供着重要的技术手段。为此,就目前水样品和食品样品中^(210)Po的处理方法及对应方法的回收率情况、^(210)Po的分析测量方法、各方法存在优势和不足以及未来样品分析测量方法的趋势进行综述,为食品样品及水样品的测量提供参考。

Polonium （Po） is a kind of very scarce element with strong radioactivity, and Po is one of alpha radionuclides of uranium series and is one of the products of relative longer radionuclides of radon decay, and its toxicity is extremely high. 210Po can enter human body by drinking water and food chain, and its internal exposure for human body is important component of public exposures. The advanced 210Po measurement method provides important technique method and guarantee in ensuring public health safety and radiation prevention. Therefore, aimed at the treatment method of 210Po in water samples and foodstuff samples and the corresponding recovery rates of this methods, the analysis and measurement methods of 210Po, the advantages and disadvantages of each method and the trend of analysis and measurement method for samples in future are summarized so as to provide a certain scientific guidance for the measurement of foodstuff samples and water samples.
