摘要

This study deals with the measurements of radon and physicochemical properties of ground water from 34 natural spring (12 springs, 15 public fountains, and seven wells) in the region of Metohija. Radon concentration in water was measured by the alpha spectrometric method using the RAD7H2O device. The mean value of radon concentration in drinking water was 11.7 Bq l−1. Mean value of estimated total annual effective dose (ingestion + inhalation) of radon was 30.8 μSv y−1. Physical and chemical properties from water’s natural sources expressed through the mean values of pH, electrical conductivity (EC), total dissolved solids (TDS), and temperature were: 7.6, 458 μS cm−1, 231 ppm, and 19.6 °C, respectively. Statistically processed data showed a strong correlation between EC and TDS - r2 = 0.94. When observing the correlation between radon in water and other investigated parameters, it can be said that only between EC and radon in water is there some correlation - r2 = 0.27. The Kruskal Wallis test (α < 0.01) indicated a significant difference between radon concentration in the public fountains and wells. Additionally, the mean value of ambient dose equivalent rate of gamma radiation measured at each sampling site using RADEX RD1503 + device was 110 nSv h−1. The spatial distribution maps of analyzed parameters, radon in water samples, and annual effective doses for adults and children in the Metohija region were created.
