New Viimsi Parish water treatment plant (Northern Estonia) was investigated in order to determine whether the open filter columns serve as a source of (222)Rn generation in the treatment process and whether they influence indoor air (222)Rn activity concentrations. (222)Rn measurements of indoor (222)Rn were performed at different locations of the treatment plant; water samples from incoming raw water, from all the purification stages, consumers water and solid filter material from two filtration stages were analyzed.
对新维姆西教区水处理厂（爱沙尼亚北部）进行了调查，以确定开放式过滤柱在处理过程中是否是氡-222的产生源，以及它们是否会影响室内空气中氡-222的活度浓度。在处理厂的不同位置进行了室内氡-222的测量；分析了来自进水原水、所有净化阶段、用户用水的水样以及两个过滤阶段的固体过滤材料。
