Comprehensive analysis of naturally occurring radionuclides in well water: Isotopic ratios, mitigation, and dose assessment.

In Sweden, around 20 % of the potable water comes from groundwater sources and about one million people drink water from their private wells. In areas with moderate or high abundance of naturally occurring radionuclides in the bedrock, the groundwater could be enhanced with radio and chemically toxic elements such as uranium, radium, lead and polonium. Therefore, this study aims to carry out a comprehensive analysis of the behaviour and radiological impact of naturally occurring radionuclides in well water.

In the Czech Republic, underground or mixed source water treatment plants are classified as the workplaces with possible increased exposure from a natural source of radiation. When releasing waste materials or residues from these NORM workplaces into the environment, the content of natural radionuclides is measured and compared with the clearance levels established by Czech legislation. The content of natural radionuclides in solid samples is determined primarily by high-resolution gamma-ray spectrometry.

The purpose of the study was to assess the radiological risk to users and the environment related to the Glo system used to heat tobacco. The concentration of Po, radioactivity per cartridge, and radiation dose assessment were evaluated. For comparison purposes, to present the exposure scale, the same analyses were also performed for several traditional cigarettes.

An extensive study on Po was conducted at Castillos Lagoon, a shallow brackish lagoon on the east coast of Uruguay, aiming to determine the activity concentrations of Po in various compartments and to derive the activity fluxes among them. The activity concentration of Po was determined in water, sediments, six different species of fishes, crabs, shrimps, phytoplankton, and zooplankton. Po was determined using alpha spectrometry, performing radiochemical separation and self-deposition on silver disc.

The enhancement of natural radioactivity in groundwater, specifically in natural mineral water, is related to the lithological formations through which water bodies or courses pass. Although natural mineral waters are exempt from monitoring for radioactive substances according to Council Directive 2013/51/EURATOM, this study focuses on the radiological characterization of natural mineral water under Spanish Royal Decree 3/2023. The water studied was taken from Catalan aquifers with different lithological characteristics (sedimentary, metamorphic or granitic) and is sold on local markets.
