Natural radionuclides 226Ra, 228Ra, 210Pb and 210Po activity concentrations and the inorganic chemical composition were determined in radioactive mineral water springs from the Water Parks of Águas de Contendas and Lambari, located in the Water Circuit of the state of Minas Gerais, Brazil. Radionuclides were determined by gross alpha and beta measurements and alpha spectrometry, and the chemical elements by ICP-OES. Among the radionuclides analyzed, the highest activity concentrations obtained were for 226Ra and 228Ra and the chemical elements Ca, Fe and Na presented higher values of concentrations. Pearson’s correlation coefficient analysis was performed to verify the correlation between natural radionuclides and the chemical elements.

巴西 Águas de Contendas 和 Lambari 矿泉水中测定的天然放射性核素 226Ra、228Ra、210Pb 和 210Po 以及无机化学元素

天然放射性核素 226Ra、228Ra、210Pb 和 210Po 的活性浓度和无机化学成分是在来自巴西米纳斯吉拉斯州水回路的 Águas de Contendas 和 Lambari 水上乐园的放射性矿泉水中测定的。放射性核素通过总α和β测量以及α光谱法确定,化学元素通过ICP-OES确定。在分析的放射性核素中,获得的最高活度浓度是 226Ra 和 228Ra,化学元素 Ca、Fe 和 Na 的浓度值较高。进行 Pearson 相关系数分析以验证天然放射性核素与化学元素之间的相关性。
