Abstract

A natural radioactivity on 21 best sold bottled mineral waters produced in Lombardia (Northern Italy) has been monitored. Gross alpha- and beta-activities were first evaluated; subsequently 226Ra and uranium were measured, by emanometric technique and ICP-MS, respectively. In order to assess with higher accuracy the dose contribution due to uranium isotopes in most active waters, 234U, 235U and 238U were determined by alpha spectrometry on electrodeposited samples. 234U/238U ratios were found to be higher than 1 in most cases. A correlation with chemical parameters of waters has also been attempted. Dose calculation for different classes of age was finally performed.
