222Rn and 226Ra concentrations in some selected samples of fertilizer of common use collected from the Iraqi market were estimated using CR-39 detectors. The average value of 222Rn and 226Ra concentrations is found to be (350.08±20.81) Bq m-3 and (4.75±0.25) Bq kg-1, respectively. The highest radon exhalation rate was found in Uzbek fertilizer. The values of effective radium are less than the recommended value of 370 Bq kg-1. The study result shows that the radon gas concentration in all fertilizers samples is below the recommended limit by International Commission of Radiation Protection agency (ICRP).
