“…Radon-attributable lung cancer deaths for all 66 countries totaled 226,057 in 2012 and represented a median of 3.0% of total cancer deaths [77]. Recently, multiple published studies have measured the risk of developing lung cancer following residential or occupational radon exposure in various regions of the world, as well as the synergistic effect of cigarette smoking and the effect in never-smokers [8][9][10]73,[77][78][79][80][81] as well as analyzing the histological types of lung cancer [82].…”

(1) Background: The association of radon-222 with lung cancer is well studied. The aim of the study was to validate a model of indoor radon measurements, to apply radon software to estimate lung cancer cases that are attributable to radon and to study the relationship between radon and earthquakes. (2) Methods: Different data detectors were used to obtain radon measurements in different places. Continuous data collection and predictions of indoor radon concentrations were carried out. Software was used to assess radon-attributable lung cancer cases, and data related to earthquake magnitudes were downloaded from Italian Vulcanology Institute. (3) Results: As expected, the highest radon concentrations were observed on the ground floor (232 ± 232 Bq/m3), with higher values measured during winter than in other seasons. The comparison of the detectors showed the overlapping of the two detectors-measured data sets. The cases of lung cancer that were attributable to radon in Locorotondo were studied (3.66/10,000). From the multivariate analysis of the relationship between high radon concentrations and high earthquake magnitude values, they show statistically significant ORs of just over 1. (4) Conclusions: Although the measured values are, on average, within the reference level, prevention measures must be implemented, as the measured radon values allow us to estimate an expected value of 3.66 cases of lung cancer per 10,000 people in the resident population.

In the present work, it had been measured the concentration of radon gas (CRn) for (10) samples of cement used in constructions before and after painting them using enamel paint, purchased from the local markets, to see the extent of its ability to reduce emissions of Rn-222 in the air. These samples were obtained from different sources available in the local markets in Baghdad and other provinces. The measurements were done by the American-made detector (RAD7). The results showed that the highest CRn in the air emitted from cement samples after coating was in the cement sample (Iranian origin) where the concentration was (58.27 Bq/m3) while the lowest CRn was found in building material samples in the white cement sample (Turkish origin) was (15.74 Bq/m3). In view of the present results, it has been confirmed that the concentration of Rn-222 emitted into the air in all building material samples is below the agency's permissible limit (ICRP).

“…It has been reported that naturally originated radiation is among the biggest contributors to the accumulative radiation dose that the world population receive. A persistent population exposure to radiation at a specific location, and for some period of time may be one cause of the hazards of radiation to the exposed population (L'annunzia 2016; Mirdoraghi et al 2020). The most common forms of ionization radiation are alpha particles such as 222 Rn, 226 Ra, and 238 U.…”

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.
