水中痕量210 Po 分析采用的是示踪剂的α能谱分析法。在待分析水样中加入208 Po 示踪剂，以氢氧化铁共沉淀的形式载带钋，在0．5 mol/L 盐酸体系中利用钋对银的高度选择性实现自沉积。利用α谱仪探测系统对样品源测量48 h ，根据钋同位素的对应谱分析210 Po 活度。本文讨论该法与我国现行国标、EML 及 IAEA 分析技术的差异性。

@@@@The determination of 210 Po in water samples was carried out by using of 208 Po tracer with the aid of alpha spectrometry .Adding 208 Po tracer to water samples before preliminary preparation ,the 210 Po and were co-precipitated with iron hydroxide .The polonium were auto-deposited on silver disc by advantage of its high selectiveness in 0 .5 mol/L hydrochloric acid solution .The sample source was counted for 60 hours in al-pha spectrometry system .The determination of 210 Po activity was performed according to different spectra .In addition ,the article discusses the differences of the present analytical method and the national standards ,EML and IAEA methods . 208 Po
