“…The biggest lifetime risk, resulted from water intake, was seen in the sample M6, while the lowest lifetime risk was found in the sample M15. The lifetime risk from ingestion of 222 Rn and 226 Ra in water samples for the inhabitants of some Marshes in Dhi-Qar Governorate, Iraq, was found ranging from 1.61 Â 10 À4 to 9.74 Â 10 À4 with an average value of (4.34 + 0.47) Â 10 À4 , which exceeds the admissible limit of 10 À4 (Alomari et al 2019). Figures 6 and 7, show the maps of total AED and lifetime cancer risk respectively in the water samples of Marshes (Ahwar) at Dhi-Qar Governorate, that were drawn by GIS technique, with ArcGIS 10.7.1, where different colors were used to distinguish between high, medium, and low quantities of these radioactive elements in drinking water.…”

Radon (222Rn), radium (226Ra) and uranium (238U) concentration in the samples of marshes' water have been measured. The samples were collected from various places at the marshes, in Dhi-Qar governorate. The method that used in the present study is the can technique by Solid State Nuclear Track Detectors (SSNTDs) with CR-39 detectors. Also, it was determined the average internal effective dose risk (AED), with lifetime cancer risk due to ingestion of 222Rn and 226Ra in drinking water. The average values of 222Rn, 226Ra and uranium 238U concentration in water samples were found to be 288.02 ± 31.21 Bq/m3, 0.45 ± 0.04 Bq/L, and 0.60 ± 0.06 ppm respectively. The average values of AED (in mSv/y unit) caused by ingestion of 222Rn and 226Ra in the samples of the study were found to be 0.019 ± 0.002 and, 0.093 ± 0.01, respectively. The average values of total AED and lifetime cancer risk values were calculated to be 0.11 ± 0.01 mSv/y and (4.34 ± 0.47) × 10−4, respectively. The average concentration values of 222Rn and 226Ra were found to be within the global average limitations (0.4 Bq/L), and (1 Bq/L) that are recommended by World Health Organization (WHO) 1993 and 2011, while the average of 238U concentrations were higher than that of global average limitation (0.566 ppm) that was recommended by Environmental Protection Agency (EPA). When some results of AED due to 222Rn and 226Ra concentrations, in the samples under study, were compared with the worldwide median value, that is recommended by WHO (2011); it was found that the lifetime cancer risk in all samples of the present study were higher than the safety limit for the healthy drinking water. Therefore, consuming the water of Marshes in the Dhi-Qar governorate- Iraq, for cooking and drinking (which is contaminated with alpha emitters like; 222Rn, 226Ra, and 238U) may lead to a considerable variation in the internal effective dose. HIGHLIGHT In this manuscript, I have been affording in a truly innovative way the issue to put the basis towards the realization for the first time of a baseline for assessment of the exposure of Iraq's people to lifetime cancer risk and annual effective dose assessment due to alpha emitters concentrations in water of Marshes in Dhi-Qar Governorate, Iraq. The results show that the cancer risk in samples is higher than the world.

“…The leakage of detergents containing radionuclides into surface water and groundwater leads to potential health hazards and environmental impacts (El-Taher & Abdelhalim, 2013). Several studies were conducted to measure the radioactivity levels in groundwater in different regions to assess the radiological risk for public and environment, where these studies showed a high level of radioactivity in groundwater in some regions (Abdurabu et al, 2016;Alomari et al, 2019;Alseroury et al, 2018;Maxwell et al, 2015;Shabana & Kinsara, 2014).…”

Phosphate ore, which may be associated with natural radionuclides, has been used for a long time as a builder in detergents. The daily use and discharge of detergents in wastewater may lead to the accumulation of radionuclides in the environment. Therefore, the current study was carried out to determine the radioactivity levels of 226 Ra, 232 Th, 40 K, and 238 U in 15 samples of detergent powders that are widely used in Saudi Arabia, using gamma-ray spectrometry (HPGe). The results showed that these radionuclides were below or similar to the recommended limits, except 238 U in two types of detergent powders. Further, radium equivalent activity (Ra eq), the outdoor and indoor absorbed dose rate (D), and annual effective dose (E) were calculated to assess the radiological hazard effects due to radionuclides in detergent powders. The results indicate that the analyzed samples of detergent powders are safe for consumers and the environment.

“…Typical radon activity in groundwater ranges from 3.7 Bq/L to 370 Bq/L and is heavily dependent on the area's geology [4]. In areas where uranium content in rocks is low, radon content in groundwater is also low (no more than several dozen Bq/L) [5][6][7]. However, it is not uncommon A technology of drinking water decontamination from radon and its decay products to fi nd thousands and tens of thousands of Bq/L in water in some countries in Northern Europe, as well as in Czechia and Russia (Ural) [8][9][10].…”

AbstractUnderground water is one of the main sources of radon for households. This article focuses on the estimation and removal of radon from underground water using the technology and inorganic sorbents developed by EKSORB Ltd., Russia for liquid radioactive waste treatment in the nuclear power industry. The article presents the results of tests of a system for the removal of radon and radon daughters from water patented by EKSORB. This is achieved by filtering water through RATZIR sorbent, followed by periodic load regeneration. Over a period of three years, the plant is successful in removing radon from the water that had an initial radon content of approximately 1500 Bq/L to less than 60 Bq/L, without releasing radon to indoor/outdoor air.
