It is known that inhaling and swallowing radon gas has raised concerns about its health risks to humans due to exposure to radon gas. In this study, the SSNTD device was used to detect the nuclear pathway of the solid-state laxative to estimate radon gas concentration in 18 soil samples randomly collected from the eastern part of Basra in southern Iraq. Concentrations of radon gas obtained using alpha (Lexan reagent) according to the technique of distribution inside a closed container, to assess the effective dose rate for travelers resulting from exposure to radon gas and its products. The results indicate that the average value of Radon gas concentration is and the annual effective dose is in Abu Al Khasib city. While the average results obtained in Ad Dayer city of Radon gas concentrations and the annual effective dose are, and respectively. All the results obtained within the acceptable limits by (ICRP) and (WHO). So, the soil is suitable for construction purposes without any health hazards.
