Assessment of Radioactivity Levels and Radiological Hazards Indices in Plant Fertilizers Used in Iraqi Kurdistan Region Saddon Taha Ahmad Koya University/ School of Medicine/ http://koyauniversity.org Abstract: The present study is to determine the activity concentration of radioactive nuclide in plant fertilizers used in agriculture in Iraqi Kurdistan region using high- purity germanium detector (HPGe) gamma spectrometer. The results showed that the range of activity concentrations for 226Ra, 232Th, 40K and 137Cs in chemicals and organic fertilizers are (0.1–134), (0.1–74), (1–12,000) and (0–1) Bq/kg respectively, based on the measured activities that were used to assess the radiological hazards. Radium equivalent activity in some samples exceeds the value (370 Bq/kg) which recommended by the OECD. Date: 4/29/2019 Place: Koya University/ SMED/ A1 Hall |
