Abstract
In this research take samples of imported chicken bones (Brazilian and Turkish) and domestic as well as sample of fish bones of domestic and imported, in order to measure and compare the concentrations of uranium in these samples using nuclear track Detector CN-85 through the density of track of alpha particles on the surface and radon concentration in the air and then find effective radon and the number and weight of the uranium atoms in the sample and thus find concentration unity ppm., and measurement using nuclear track detector CN-85, as was samples preparation scientific way and according to several sources in this area. After a long period of time (60) days, the samples were collected and chemically treated according to scientific sources, then the track number were calculated using an optical microscope The results showed for the chicken bones that the highest concentration of uranium was in the chicken Turkish and reached (4.59ppm), and less concentration was in Brazilian chicken and (1.52ppm), either chicken Iraqi value was (3.4ppm), compared with background radiation amounting to (1.12 ppm). For Fish was the concentration of uranium in importer frozen (3.53ppm), and this value is higher than the concentration in fish is Iraq, which was (2.15ppm), compared with the background radiation of (1.12 ppm)
