Measurement the Effectiveness of Radiation and Physiochemical Properties of Soils Selected from Diwaniya City, Iraq

The natural radiation of soil samples in the Aaldewanah city, Heavy metals (HMs), and physiochemical parameters of twenty different public sites. The results showed that values of activity concentrations of 238U and 40K were lesser than level of (MCL) proposed by United States Environmental Protection Agency (USEPA) But 32Th is slightly higher than the limit values because of the global nature of the soil Jalogih. The average values of the Radium equivalent activity and annual effective dose were less than the world average, the heist external and internal, hazard and gamma activity concentration index were lower than unity. Hydrogen ion concentration (pH), Electrical conductivity (EC), Salinity (Sal. ), and heavy metals (HMs) ; Cr, Co, Cu, Mn, Zn, Cd, and Pb for the soils under study has been examined. The results showed a great variation among the analyzed samples with respect to their physical and chemical parameters. However, most values were higher the maximum permissible levels recommended by world health organization (WHO).
