“…Similarly, the recorded radon concentrations were compared with the European Commission (EU 2001) recommended action level of 100 Bq/L for pubic water supplies; and it was apparent that radon concentration exceeded the action level in 20% of samples (viz., 13 groundwater samples). The mean and the range values of radon concentration recorded in the present study are on higher side compared to the result reported by Kumar et al (2017) Prasad et al (2009) as the latter reported radon concentration ranging from 8-3047 (average: 510 Bq/L) in the groundwater collected and analyzed from parts of Garhwal Himalayas, India. Figure 3 and it well fits to a typical log-normal distributions.…”

“…A wide range of variation in the radon concentration level is subject to origin of water source. Thus, it is very essential to assess the presence of this radionuclide in different water sources, particularly underground sources (Fonollosa, et al 2016) in order to protect the population from consequence of excessive internal radiation exposure from 222 Rn (Kumar et al 2017). Many researchers (Binesh et al 2010(Binesh et al & 2011Fakhri et al 2016;Somlai et al 2007) have recorded significant differences between the effective dose received by infants, children, and adult men and women by using higher conversion factor for infants and children and lower dose conversion factor (DCF) for adults according to their radio-sensitivity.…”

“…and Panghal et al (2017);Kumar et al (2017) documented comparatively low levels of radon ranging from 2.80 to 74.37 Bq/L (average: 29.37 Bq/L) in water samples from Reasi district, lesser Himalayas of Jammu and Kashmir State, India, whilePanghal et al (2017) reported the levels of radon to vary from 16.06 to 57.35 Bq/L (average: 32.98 Bq/L) in the drinking water samples of four districts of Haryana, India. On the other hand, the present results were on the lower side when compared with the results of…”

Ingesting waters holding high levels of natural occurring radioactive element like Radon would contribute to increase in the effective dose received by people followed by an increased prevalence of cancer. The current study is an attempt to describe the extent of contribution of 222 Rn to natural background radiation and the resultant effective dose to public of different age groups. In order to do so, 65 groundwater samples from selected parts of Bangalore city were collected and analyzed for radon activity using RAD7 radon monitor coupled with RAD H 2 O accessories. The radon activity was in the range of 3.05-696 Bq/L (mean: 91.39 Bq/L) and 92.31% of the groundwater samples recorded elevated radon concentration above the United States environmental protection agency (USEPA's) Maximum Contaminant Level (MCL) value of 300 pCi/L, corresponding to 11.1 Bq/L. The mean annual effective dose contribution of people falling under different age groups (viz., infants, children, teens: males and females, adults: males and females, pregnant and lactating women) due to ingestion of water-borne 222 Rn ranged from 0.082 to 0.444 mSv/y and was found to be higher in all the age groups of males compared to respective female age groups, but well within the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) and World Health Organization (WHO) proposed limit of 1 mSv/y.

“…The activity concentrations of 222 Rn and 220 Rn in some dwellings of study area were also measured by Smart RnDuo monitor (active technique). The advanced SMART RnDuo (active technique) is manufactured by Bhabha Atomic Research Centre, Mumbai, India for the measurement of 222 Rn and 220 Rn concentration in air, water, and soil [45,46]. The observed concentrations of radon 222 Rn and 220 Rn by smart RnDuo monitor are found to be in fare agreement with passive dosimetry (pinhole dosimeter) as given in Table 6.…”

Background The inhalation doses resulting from the exposure to radon, thoron, and their progeny are important quantities in estimating the radiation risk for epidemiological studies as the average global annual effective dose due to radon and its progeny is 1.3 mSv as compared to that of 2.4 mSv due to all other natural sources of ionizing radiation. Objectives The annual inhalation dose has been assessed with an aim of investigating the health risk to the inhabitants of the studied region. Methods Time integrated deposition based Rn/Rn sensors have been used to measure concentrations in 146 dwellings of Udhampur district, Jammu and Kashmir. An active smart RnDuo monitor has also been used for comparison purposes. Results The range of indoor radon/thoron concentrations is found to vary from 11 to 58 Bqm with an average value of 29 ± 9 Bqm and from 25 to 185 Bqm with an average value of 83 ± 32 Bqm, respectively. About 10.7% dwellings have higher values than world average of 40 Bqm prescribed by UNSCEAR. The relationship of indoor radon and thoron levels with different seasons, ventilation conditions, and different geological formations have been discussed. Conclusions The observed values of concentrations and average annual effective dose due to radon, thoron, and its progeny in the study area have been found to be below the recommended level of ICRP. The observed concentrations of Rn andRn measured with active and passive techniques are found to be in good agreement.

“…Radon concentration in the underground water in this study was determined by using RAD H 2 O was used. 15 A watt-250 protocol along with Grab mode was chosen on the RAD-7 for 250 ml samples. The internal pump was used to obtain radon from the water sample and it circulates the gas to the counter for measurement.…”

This research measured the concentration levels of radon in groundwater and determined the ingestion and inhalation dose. The study used RAD7 detector with RAD7-H2O accessory from Durridge Company to determine the radon levels. Thirty water samples in granitic dominated regions were collected from various areas of Bungoma County: ten from boreholes (BH), ten from hand dug wells (WL) and ten from springs (SP). The water samples were collected in 250 ml bottles which were tightly covered with lid to avoid radon leakage. The highest value was 303±4.00 KBq/m3 recorded in Kanduyi well and the lowest was 126±11.4kBq/m3 from where most of the samples recorded a high radon concentration with a mean of 269±5.25 KBq/m3 in wells, 213±7.96 KBq/m3 in boreholes and 290±7.70 KBq/m3 in springs. The average ingestion dose was found to be 1.5±0.07mSv/yr, 1.9±0.09 mSv/yr and 2.1±0.1 mSv/yr. The average annual effective dose rate for the samples collected were 2±0.1 mSv/yr for boreholes, 2.6±0.13 mSv/yr for wells and 2.7±0.14 mSv/yr for springs. The samples reported an average value of AED higher than the world average of 1.15 mSv/yr but below the exception limit of recommended action level of 10 mSv/yr hence the radon concentration levels in underground water in the study area has minimal health implications to the population.
