• The assessment of the primordial radioactivity levels and associated risks to the manufacturing process of the single super phosphate fertilizer (SSPF) has been performed. Samples from different stages were collected from hot spots including ores inputs storages and production of phosphate fertilizer factory at Kom-Oshim Fayoum, Egypt. According to the gamma spectrometric analysis, 226 Ra values ranged from 511 ± 45 to 882 ± 65 Bq kg –1 , 238 U values ranged from 500 ± 60 to 919 ± 45 Bq kg –1 , 232 Th values ranged from 3.9 ± 0.4 to 8.1 ± 0.3 Bq kg –1 , and 40 K values ranged from 5.4 ± 0.7 to 210 ± 1.9 Bq kg –1 . Radiation indices for these samples were calculated and found to be higher than the world average values. The ambient dose rates of the factory site were monitored and found to vary from 0.06 to 0.11 (µSv/h).
