Activity of ²²²Rn in Tap Water in Kielce County

Radon is known as a radioactive element that dissolves easily in water. It is worth mentioning that it is available in all possible reservoirs. Its concentration cannot be measured directly but only from the emitted radiation. Investigations of ²²²Rn activity in water in the Kielce district were subjected to three selected water intakes: Bolechowice, Kołomań and Wola Kopcowa. This type of research was conducted for the first time in the discussed area. The results were analyzed in detail in terms of acceptable concentrations. Next, it was determined whether the geological location of the intakes in question may have an impact on the amount of radon present in water from the water supply network.
