“…The equilibrium factor for thoron and its progeny varies from 0.004 to 0.09 with an average of 0.02 which is comparable with value of 0.02 given by UNSCEAR [22]. radon concentration was found in Shiwalik region due to its geology (cobble, pebble and gravel, granite, red purple shales, clays), soil, and source term conditions [41]. The maximum thoron concentration was found in Murree region having Purple/Red colored sand and clay which are rich sources of thorium.…”

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.

“…Various pollution indices such as geoaccumulation index (I geo ), enrichment factor (EF), contamination factor (CF), pollution load index (PLI), and potential ecological risk (RI) that are widely used to evaluate pollution by heavy metals in surface agricultural soils (Mazurek et al 2017;Gąsiorek et al 2017;Oumenskou et al 2018;Kumar et al 2018;Barakat et al 2019a) have been used in this study. The pollution indices are presented in Table 1.…”

The present study investigated the potentially toxic heavy metal (Cu, Pb, Zn, Cr, and Cd) contamination and its ecological impact in the agricultural soil in the northeast part of Tadla plain (Morocco). A total of 60 subsurface composite samples were collected and analyzed to determine pH, soil organic matter (SOM) and texture, and heavy metal concentrations. Pollution levels were assessed by adopting enrichment factor (ef), geoaccumulation index (I geo), contamination factor (CF), pollution load index (PLI), and ecological risk index (RI). The results showed that the average concentrations of Cd, Cr, Cu, Pb, and Zn in the collected 60 topsoil samples were 0.92, 32.72, 138.10, 31.72, and 162.11 mg/kg, respectively, and followed the order Zn > Cu > Cr > Pb > Cd. These concentrations exceeded acceptable thresholds of the World Health Organization (WHO) and Food and Agriculture Organization (FAO) and local background. From the Principal Component Analysis (PCA) results showing no correlation between the soil properties and heavy metal contents, suggesting that the metal elements were of different sources, especially anthropogenic. The mean RI values of 65.68 indicated a low ecological risk and indicate that the study area is moderately to strongly pollute in the case of Zn and Cu and partly influenced by human activities. Nevertheless, this study provided important information for policymakers to propose an appropriate plan for pollution control in the agricultural Tadla plain.

“…In recent years, uranium and radon as emerging contaminants are reported from various parts of India and reported by Kumar et al (2018b) Kumar et al (2018a). Similar studies of high uranium in groundwater and its impact on human health in Punjab has been carried out by Bajwa et al (2017), Narang (2018), Sharma et al (2018) and Sharma et al (2019.…”

The hydrogeology of India represents one of the diverse systems in the world. The hydrologically distinct Himalayan highlands and its foreland basins with deposits of indo-Ganga Brahmaputra system gradually merges with the cratonic provinces of central and south India, fluvioaeolian deposits of west and the basaltic province of the Deccan plateau. The tremendous socio economic significance of groundwater in India can be appreciated by the fact that about 62 % of water used in irrigation, about 85 percent of rural water supply and more than 50 % of urban water consumption is extracted from aquifers.The acute over-exploitation of groundwater resources in some parts of India, deterioration in groundwater quality both from geogenic and anthropogenic sources, declining well yield, the quest for sustainable use of groundwater resource and the need to map and understand the aquifer system have acted as stimulus for researchers throughout India. The paper deals with a brief introduction of Indian hydrogeology and reviewed the huge volume of researches carried out in the recent past under nine sub themes representing the rainbow of groundwater research in India.
