Nuclear and radioactivity studies

New Viimsi Parish water treatment plant (Northern Estonia) was investigated in order to determine whether the open filter columns serve as a source of 222Rn generation in the treatment process and whether they influence indoor air 222Rn activity concentrations. 222Rn measurements of indoor 222Rn 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.
