In this article, authors report experimental results obtained for the assessment of gross alpha and beta radioactivity in drinking waters, coming from the Calabria region, southern Italy. The measurements, performed with the Perkin-Elmer Tricarb 4910 TR Liquid Scintillation Counter (LSC) setup, were compared with reference values derived from Italian regulations (the Italian Legislative Decree n. 28/2016) to evaluate the existence of possible health risks for the population due to the ingestion of gross alpha and beta radioactivity in the analyzed drinking waters. Experimental results underline that both specific activities in the investigated drinking waters varies widely. In particular, for gross alpha, the activity concentration ranges from a minimum value lower than the LSC minimum detectable activity (MDA), 0.04 Bq L⁻¹, for the site IDs 13, 28, 34, 35, 38, 44, 53, to a maximum of (0.16 ± 0.03) Bq L⁻¹ for the site ID 22; for gross beta, the specific activity varies from a minimum value lower than the LSC MDA, 0.20 Bq L⁻¹, for all the sampling sites except for the site IDs 5, 6, 9, 13, 15, 18, 19, 25, 27, 29, 33, 34, 40, to a maximum of (0.34 ± 0.07) Bq L⁻¹ for the site ID 15. Obtained results represent a main reference for the investigated area, and they are useful to determine the associated radiological health risks for the population.

在本文中，作者报告了来自意大利南部卡拉布里亚地区的用于评估饮用水中总α和β放射性的实验结果。将使用Perkin-Elmer Tricarb 4910 TR液体闪烁计数器（LSC）设置进行的测量与源自意大利法规（意大利第28/2016号法令）的参考值进行比较，以评估存在潜在的健康风险由于在分析的饮用水中摄入了总的α和β放射性，导致人口数量增加。实验结果表明，所研究的饮用水中的两种特定活性差异很大。特别是，对于总阿尔法，活性浓度的范围为比LSC最小可检测活性（MDA）低的最小值0.04 Bq L对于站点ID 13、28、34、35、38、44、53，^-1，对于站点ID 22，最大值为（0.16±0.03）Bq L ^-1；对于站点ID 22，最大值为（0.16±0.03）Bq L ^-1。对于总β，比活性而变化从最小值比LSC MDA降低，0.20贝大号^-1，对于除了网站ID 5，6，9，13，15，18，19，25的所有的采样点， 27、29、33、34、40 ，对于站点ID 15的最大值（0.34±0.07）Bq L ^-1。获得的结果是所研究区域的主要参考，对于确定相关的放射健康状况非常有用人口风险。
