Abstract

A radiochemical procedure has been developed for the quantification of uranium and thorium isotopes in NORM samples from the ceramic industry, such as zirconium sands, zirconium flours, micronized zircon, pigments and personal aerosol filters. The method is based on a fusion pretreatment with borate salts, a separation with anion exchange resins and alpha-particle spectrometry measurement. This method is an alternative to gamma spectrometry when the amount of sample is extremely small (2–10 mg) as in the case of aerosol filters, or there is no secular equilibrium in the 238U and 232Th chains, as in the ceramic pigments. The method has been validated with different ceramic materials and the comparison of the results with gamma measurements. Its reproducibility was also checked with different sample masses.

利用阿尔法粒子光谱法测定陶瓷工业中 NORM 材料中的铀和钍同位素
已开发出一种放射化学程序,用于定量检测陶瓷工业中锆砂、锆粉、微粉锆石、颜料和个人气溶胶过滤器等非放射性核素样品中的铀和钍同位素。该方法基于硼酸盐的熔融预处理、阴离子交换树脂的分离以及α-粒子光谱测量。当样品量极少(2-10 毫克)(如气溶胶过滤器),或 238U 和 232Th 链(如陶瓷颜料)没有达到长期平衡时,这种方法可以替代伽马能谱法。已用不同的陶瓷材料对该方法进行了验证,并将结果与伽马测量结果进行了比较。此外,还利用不同的样品质量检验了该方法的可重复性。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
