Measurement of radioactive pollution in the dust storms of the city of Tikrit by using the nuclear track detectors CN-85

This research was a study of radioactive pollution of the dust storms of the city of Tikrit, where samples they were collected for two consecutive years (2010-2011) and by eight samples were identified as concentrations of radon( Rn-222) using nuclear track detector (CN-85) The results of the study showed an increase in radon concentrations ranged from (0.8-1.05ppm)and compared with the amount of background radiation (0.05ppm) This refers to the presence of radioactive pollution , as well as the dust storms are frequent and frequently led to increased concentrations of radon Any increase in concentration of mobile molecules by any air increases the likelihood of the arrival of these molecules to the lung
