Abstract
In present study, radon concentrations were measured for some fertilizers samples . These samples were collected from local markets of Najaf province, Iraq. CR – 39 plastic track detectors were used as measurement device with cylindrical diffusion technique. Also, radon exhalation rate was estimated for all samples under study. The results demonstrate that, the value of radon concentrations were ranged from 1.39 Bq/m3 to 593.06 Bq/m3 with an average of 101.23 Bq/m3, while the values of radon exhalation rate were ranged from 1.01 mBq/m2.h to 439.89 mBq/m2.h with an average of 73.72 mBq/m2.h. It is found that radon exhalation rate for all fertilizers samples were below the maximum permissible limit 57.6 (Bq/m2.hour), so it can be concluded that the samples under study may have no health risks.
