Studying the Existence of the Hidden Deadly Radioactive Radon Gas in Some Houses in Al-Ajilat City

This study was conducted to detect the presence of the hidden radioactive and deadly radon gas in 10 houses in Al-Zaramaqa area in the city of Al-Ajilat, using a solid-state device (RADEX MR107) for detecting the presence of this gas in buildings of various types. Through this study, the results showed that this gas is present in different proportions depending on the location and design of the building, as well as the type of building materials used in its construction, and the ventilation system employed in the area where the study was conducted. It was found that the radon values in the buildings under study ranged between 28 and 59 Bq/m3. It was also found that these values obtained fall below the dangerous and non-permissible values referred to by the World Health Organization, estimated at (200 Bq/m3) and therefore they are considered within the low risk levels. Lung cancer is one of the most serious consequences of exposure to this radioactive gas. Given the study's limited number of buildings and areas covered, it cannot be concluded that there are no other buildings in the city of Al-Ajilat with high radon concentrations.
