“…It can be concluded from Table 2, the activities of alpha due to radium in water samples were found to be lower than those caused by radon. These observations can be clarified by the fact that radon has the shorter halflife (3.82 d) than that of radium (1,600 y) (Elzain 2014;Abojassim & Mohammed 2017;Abojassim et al 2017aAbojassim et al , 2017b. The results of C s,ac Ra for samples of water in the present study were found to be within the global average limitations (1 Bq/L) that are recommended by WHO (2011), except Sample M6 was larger than global average limitations.…”

“…The samples were set at the bottom of the cylinders, then the cylinders were sealed, and stored at room temperature for 90 days (exposure time). At the end of the exposure time, the CR-39 detectors were etched of sodium hydroxide (NaOH) solution at (70)°C temperature for (5) hours, with (6.25) normality solution (Abojassim & Mohammed 2017;Abojassim et al 2017aAbojassim et al , 2017b. Following this step, the detectors were washed using distilled water.…”

“…Geographic Information System (GIS) technology has been widely used in various fields, such as agriculture, business, geography, ecology, electricity and gas, emergency management and public safety, environmental management, forestry, health care, education, mining and geosciences, real estate, remote sensing, telecommunications, transportation as well as water distribution and resources (Abojassim & Rasheed 2019;Saleh et al 2019;Kiani et al 2021). The study of natural radioactivity (alpha emitters) was carried out by many investigators in different countries around Iraq and others throughout the world (Abbasi & Bashiry 2016;Abojassim & Mohammed 2017;Abojassim et al 2017aAbojassim et al , 2017bEl-Taher et al 2020). Many regions in the Dhi-Qar governorate have been bombarded In the recent wars that Iraq was exposed to in the previous period.…”

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.
