“…In this research 18 % of total samples (15 samples of 82 samples) radon concentrations are above recommended limits by EPA. Almost that result was consistent with results of this research (21) . A study was conducted in 2014 in Iran by Malakootian and colleague on the sources of drinking water and also drinking water network of Mehriz villages of Yazd province.…”

Background: Radioac ve substances are water chemical contaminants. In this study, the concentra on of radon was measured in drinking water supplies of Ta villages (part of Dehshir-Ba fault located in central part of Iran) and also Shirkooh area with granite rocks (containing uranium). Materials and Methods: This cross sec onal research was conducted in fall 2013 and winter 2014 on the sources of drinking water and also drinking water network of Ta city of Yazd province. According to the measured radon levels; the annual effec ve absorbed dose was also calculated. Results: Minimum and maximum levels of radon gas were related to sample number 54 (0.88 BqL ). Range of radon concentra ons was 1.88-43.01 BqL -1 in samples of wells in private homes, 0.88-20.36 BqL -1 in supplier wells of public network of drinking water, 1.23-10.29 BqL -1 in aqueducts, 1.23-11.49 BqL -1 in water tap connected to the public network and 12.89 BqL -1 in one measured spring. The annual effec ve absorbed dose through drinking and breathing in an environment that this water is used ranged from 0.00 msv/y (sample No.54) to 0.11 mSv/y (sample No.31). Conclusion: Radon concentra on was lower than the limit set by the Environmental Protec on Agency of United States of America, in 82% of samples. Samples with high radon concentra ons were located around Shirkooh area due to the presence of grani c rocks. Dehshir and Garizat villages located through Dehshir -Ba fault and the Radon concentra on of these samples was less than the permissible limit, probably due to the inac ve Fault.

“…The decrease in pH results of the groundwater samples in the northwestern region of the basin (Anar plain) was caused by the sulfide volcanic rocks of the Sarcheshmeh Mountains (Dehj-Sardoueye belt), which is the main source of groundwater recharge in the Anar plain. Then, the water with low pH values was transferred to the end of the basin based on the flow gradient direction (Khajehpour and Abbasnejad, 2007;Malakootian & Khashi 2014). On the other hand, the presence of copper mines in the way of the groundwater slope toward the Anar plain caused a decrease in the pH values in the northwestern areas (Dehghan and Abbasnejad, 2011).…”

This paper investigates the suitability of groundwater for domestic and agricultural use in the Rafsanjan plain, southwest part of the Daranjir–Saghand basin, Iran. Fifty-five groundwater samples were collected and analyzed by six methods including the water quality index (WQI), Schoeller diagram, irrigation water quality (IWQ) parameters, Piper diagram, US salinity diagram and Wilcox diagram. The spatial distribution maps of chemical parameters and groundwater quality indices were plotted using the IDW method in GIS. The results showed a low concentration of major ions in the southeastern part and a high concentration from the central part towards northwestern part of the plain. The concentration of major ions in groundwater was strongly affected by groundwater flow, geological setting and the existence of the evaporative layers in the studied area. Moreover, results revealed that most of samples exceeded the acceptable limits recommended by the WHO and ISIRI1053 standards for domestic and agricultural purposes. In most of the wells, groundwater was classified into saline and very hard categories. The analyses based on WQI values indicated that above 87% of water samples were unsuitable for drinking purposes. IWQ parameters expressed that 85%, 67%, 32%, 51%, 43% and 50% of samples had EC > 3000, Na% > 60%, MAR > 50%, KR > 1, SAR > 9 and Cl− > 350, respectively, which were unsuitable for irrigation use. The dominant hydrochemical facies of water was Na–Cl–SO4 type, and 63% and 22.8% of samples were categorized as C4S4 and C4S3 class, with very high-salinity–high-sodium hazards and very high-salinity–high-sodium hazards, respectively. It indicated that most irrigated lands in this study area were affected by different levels of salinity and sodicity hazards that caused decreases in plant growth and crop productivity. The results can assist decision-makers and planners in prioritizing groundwater resources management in the region.

“…In Iran, Rahimi et al reported that the concentration of radon in drinking water resources of the Rafsanjan and Anar regions were 0.32 ± 0.12 Bq/L and 13.9 ± 2.45 Bq/L, respectively (18). In two separate studies, Malakootian et al measured the concentration of radon in drinking water resources around the Lalehzar and Rafsanjan faults as 0.74 and 26.88 Bq/L, respectively (19,20). The concentration ranges of radon dissolved in groundwater were 0.87-6.73 Bq/L in Himachal Pradesh (21) and 0.14-35 Bq/L in Punjab (22).…”

Background: Radon is a major source of natural radiation in water, soil, and air. Natural sources of radiation are major contributors to the radiation humans and other living beings receive. Methods: This cross-sectional study was conducted on drinking water sources of three cities and 18 villages of Roudan county in 2021. The measurement of radon concentration in the collected samples was performed using the RAD7 device. Results: In the studied water sources, the highest and lowest radon concentrations were 11.00±2.09 and 0.95±0.23 kBq/m3 , respectively. The average radon concentration was 4.98±0.76 Bq/L which was lower than 11 Bq/L (the EPA level recommended for drinking water). The mean annual effective dose of radon, due to direct and continuous water intake for adults and children was 48.01±11.56 and 65.86±15.86 µSv/y, respectively. Conclusion: The results of this study showed that radon concentrations in two regions of Roudan county were higher than the allowed World Health Organization (WHO) concentration and people who normally use these resources for drinking during the year are exposed to abnormal radiation levels.
