Radon Content of Recent Sediments in Relation to Tectonic Features at Mosul City and Neighboring Area

Thirty three recent sediment ( 5 surface wadi filling and 13 flood plain + 15 soil at 0.7m depth) samples were selected from different localities namely ( from south to north ) : al-sallamya + lazzaga villages, hawi al-kanessa, shuraikhan, al-mallaeen quarter, tel-kief, wadi al-malah, and fifeal area. the collected samples were subjected to traditional geochemical test and analysis in aaddition to radon gas measurement using solid plastic nuclear detector cr-39 ( columbia resin ) in the field( cup irradiation technique ) and in the laboratory ( test tube irradiation technique ). sodium hydroxide etched detector were investigated under optical microscope to count the track density and later radon gas exhalation measurements (bq.m^-3) were calculated. variation in radon gas measurements were displayed and followed in contour maps and discussed in relation to the obtained geochemical data and to know faults and other structural features in the studied area.
