Summary
In the Beiras region of central Portugal, geological pattern is characterized by granitic bedrock enclosed in metamorphic formations, enriched in lithogenic radionuclides and their progeny. Spring water, of underground origin, can dissolve some radioelements. This water is commonly drunk by the population. Therefore, the radiological risk of ingesting radionuclides, such as radon and radium through the consumption of this water, must be carefully evaluated.
The radioprotection hazard is assessed after measuring these radionuclides in water, following ICRP recommendations. The potential influence of geological characteristics at the sampling sites, together with the physicochemical properties of the samples, is investigated. Moreover, radon and radium contents are compared for understanding the origin of the dissolved radon in water.
