| Abstract | ||
| This study has been carried out to detect and measure the specific activites, radiation hazard indices of radionuclides for fertilizer samples for six available kinds [)Fertilizer Compound (NPK), Triple Super Phosphate (T.S.P.), Mixed Fertilizer (M.F.), Organic Nitrogenous (O.N.) ,Single Super Phosphate (S.S.P.) , Dicalcium phosphate (D.S.)] from different origins, by using high-purity germanium (HPGe) detector . The results obtained have shown that, the highest value of specific activity of U-238, Th-232 and K-40 were (26.070 Bq/kg, 29.850 Bq/kg ,252.720 Bq/kg), respectively, in fertilizer sample Triple Super Phosphate (T.S.P.), Jordan origin while the lowest value of specific activity of (238U) was found in Dicalcium phosphate (D.S.) which was equal to (12.340 Bq/kg), Lebanese origin and the lowest value of specific activity of (232Th) was found in Mixed Fertilizer (M.F.) which was equal to (14.620 Bq/kg) , Italian origin and the lowest value of specific activity of (40K) was found in (NPK) Fertilizer Compound which was equal to (94.540 Bq/kg), Iranian origin. The present results show that the value of specific activity of U-238, Th-232 and K-40 in all fertilizer samples are below the allowed limit as well as all fertilizer samples are safe for consumption and does not constitute a danger to the citizens. | ||
