Study of Gross alpha beta radioactivity content in commercial water brands by liquid scintillation

Year: 2024

Type: article

Abstract: This study presents the Gross alpha beta radioactivity in bottled water from twenty different commercial brands. In Mexico, the official Mexican standard NOM-127-SSA1-2021 establishes the values of 0.5 and 1.0 Bq/L as limits for Gross alpha and beta radioactivity in drinking water. The analysis was carried out with the liquid scintillation method, making a concentration of 10 to obtain a minimum detectable concentration of 0.25 and 0.5 Bq/L respectively. The results obtained indicate that in all cases the bottled waters comply with the applicable standard, which in turn indicates that the effective annual dose would be less than 0.1 mSv, since this limit was calculated based on this premise, indicating that the radiological risk for the consumer is negligible according to this norm.
