Abstract. The main factors affecting the value of 222 Rn activity concentration in groundwater are the emanation coefficient of reservoir rocks (K em ), the content of parent 226 Ra in these rocks (q), changes in the volume and flow velocity as well as the mixing of various groundwater components in the circulation system. The highest values of 222 Rn activity concentration are recorded in groundwaters flowing towards an intake through strongly cracked reservoir rocks undergoing weathering processes. Because of these facts, waters with hazardous radon concentration levels, i.e. containing more than 100 Bq dm −3 222 Rn, could be characterised in the way that follows. They are classified as radon waters, high-radon waters and extreme-radon waters. They belong to shallow circulation systems (at less than a few dozen metres below ground level) and are contemporary infiltration waters, i.e. their underground flow time ranges from several fortnights to a few decades. Because of this, these are usually poorly mineralised waters (often below 0.2-0.5 g dm −3 ). Their resources are renewable, but also vulnerable to contamination.Waters of this type are usually drawn from private intakes, supplying water to one or at most a few households. Due to an increased risk of developing lung tumours, radon should be removed from such waters when still in the intake. To achieve this aim, appropriate legislation should be introduced in many countries.

“…The higher values of radon in the water samples of hand pumps and bore wells is possibly because of its greater depth, which allows water to interact with a greater thickness of aquifer and thus more radon is expected in hand pumps and tube wells [29]. This clearly indicates that the radon concentration primarily depends on the lithology, structural attributes and the presence of uranium minerals in rocks [30]. The UNSCEAR has suggested a value of radon concentration in water for human consumption between 4 and 40 Bq l -1 [31].…”

This paper presents the distribution of radon activity concentration in drinking water samples and their annual effective dose exposure in Shimoga district. The radon concentrations in 38 drinking water samples were measured by using Emanometry technique. The measured radon concentration in drinking water samples ranged between 3.10 ± 0.25 and 38.50 ± 1.54 Bq l -1 with an average value of 13.60 ± 1.12 Bq l -1 . This study reveals that 44.8 % drinking water samples analyzed have radon levels in excess of the EPA recommended maximum contamination level of 11.1 Bq l -1 . The total mean annual effective doses of all the samples are significantly lower than the reference level of 0.1 mSv y -1 .

Radon measurements were made in the soil-gas and groundwater present in various lithological units and across the major tectonic zone (Munsiari and Bhatwari-Ramgarh Thrust) located between Ghansali and Ghuttu area in Bhilangana valley of the Garhwal Himalaya, India. High concentrations of radon were observed both in soil-gas and groundwater samples located close to the tectonic planes. Overall radon concentration in this area was found to be controlled by lithology, structure and associated uranium mineralization.
