| Abstract | ||||
| In the present work, we have measured the radon gas concentration; effective dose and exhalation rate for some fertilizers samples, raw materials, triple super phosphate and single super phosphate by using alpha-emitters registrations that are emitted from radon gas in CR-39 nuclear track detector after irradiated with gamma rays. The results indicated that the highest average radon gas concentration in fertilizer samples was found in raw material, triple super phosphate (T.S.P) samples (269.620Bq/m3and 186.8 Bq/m3,respectively) while the lowest average radon gas concentration was found in single super phosphate ( S.S.P.) for powder and granules samples, 79.6 Bq/m3 and 52.90 Bq/ m3, respectively . These results show that the radon concentration; effective dose and exhalation rate in all fertilizers samples and waste product are below the allowed limit according to the International Commission of Radiation Protection agency. | ||||
