The European Union published in 2013 a new Drinking Water Directive with stricter requirements for measuring natural radioactivity. In order to adhere to this, a method for sequential separation of 210Pb, 210Po, 238U and 234U in drinking water was applied using UTEVA® and Sr resins. Polonium-210, 238U and 234U were quantified using alpha-particle spectrometry and 210Pb using liquid scintillation counting. Radium-226 and 228Ra were determined using 3M Empore Radium RAD Disks, and their quantification was done using a Quantulus™ 1220 liquid scintillation counter.
欧盟于2013年发布了一项新的饮用水指令，对天然放射性测量提出了更严格的要求。为了遵守该指令，采用UTEVA®树脂和锶树脂对饮用水中的210Pb、210Po、238U和234U进行了顺序分离。通过α粒子光谱法对钋-210、238U和234U进行定量分析，通过液体闪烁计数法对210Pb进行定量分析。使用3M Empore镭RAD盘测定镭-226和228Ra，并使用Quantulus™ 1220液体闪烁计数器对其进行定量分析。
