Determination of Radon and Uranium Concentrations in soil samples Iraqi cities

In this investigation the concentrations of radon and uranium levels in 180 soil samples distributed in 18 cities in Iraqi Country have been measured using long term technique for alpha particles emission with solid state nuclear track detecror type CR-39 . The maximum concentrations of radon was (261.54Bqm-3) in soil sample No. (18) : Basra city , while the minimum activity was (86.80 Bqm-3) in soil sample No. (6): Salahaddin city. The uranium concentrations in the same cities have been measured in (ppm) unit the maximum concentration was (0.0201) in soil sample No. (18):Basra city , while the minimum activity was (0.0067) in soil sample No. (6):Salahaddin city. The variable values of radon and uranium concentrations may be mentioned that Iraq cities have variable geologies ,despite the limitation of existing data the observational and experimental data presented here is the first investigation and study provided a basis for the radon and uranium map in whole Iraq.
