Determine the radioactive isotopes in some agricultural crops


AbstractThe specific activities of some local agricultures samples were studied in this research to identify the natural radionuclides and their specific activities values. Four samples (watermelon, pear, wheat, and pomegranate) were be taken from Al-Ruttba, Al-Faluja, and Al-Rummana farms. The studied were performed by gamma spectroscopy "high purity germanium detector" .The results showed that the samples contained potassium-40 (K40) single natural radioactive nuclide, which is the most common nuclide in nature, as well as radium-226 (Ra226 and Bismuth-214 (Bi214)) of the uranium-238 series, and lead-212 (Pb212) of the series. Thorium 232 .The highest radioactivity of potassium-40 was in the wheat sample (S3a), which was 100.85 Bq /kg, and the highest radioactivity of bismuth-214 was in the sample of pear S2a, which was 13.10Bq / kg, and the highest radioactivity of radium-226 was in the wheat sample (S3a). It is 10.15Bq / kg, and the highest radioactivity for lead-212 was in the Raqi sample (S1a), which were 1.18Bq / kg. And all these values were within permissible global limits.
