Abstract
Phosphate rocks are the raw materials for fertilizer production. This study aims to evaluate the occupational radiological hazards associated with phosphate rock processing. The average activity concentrations were 825 ± 41, 166 ± 8.3, 12 ± 0.6, and 1333 ± 67 (Bq/kg) for U-238, Ra-226, Th-232, and K-40 respectively. All these concentrations are typical for phosphate rocks. The average absorbed dose rate is 139 ± 7 (nGy/h), which is higher than the worldwide average, reflecting the relative high concentrations of U-238, Ra-226, and K-40. The average total annual effective dose is 0.53 ± 0.03 (mSv/y). All the radiological parameters are lower than the recommended limits.
