A measurement of the radioactivity content of phosphate ore material, phosphatic fertilizer (superphosphate), and by-product phosphogypsum in the Abu-Zaabal phosphate plant, Egypt, has been carried out. According to the results of gamma-ray spectroscopy analysis, {sup 238}U was found in concentrations of 523, 473, and 134 Bq kg{sup {minus}1}; {sup 226}Ra in concentrations of 514, 301, and 411 Bq kg{sup {minus}1}; {sup 232}Th in concentrations of 37, 24, and 19 Bq kg{sup {minus}1}; and {sup 40}K in concentrations of 19, 3, and 16 Bq kg{sup {minus}1} for the analyzed materials, respectively. The data are discussed and compared with those given in the literature for some other countries in light of permissible radiation dose rates. 11 refs., 3 tabs.
