Phosphate Rock - an overview ScienceDirect Topics

Sedimentary phosphate rock usually is strip-mined and contains high concentrations of 238 U (800–5200 Bq/kg), 230 Th (200–16,000 Bq/kg), 232 Th (5–170 Bq/kg), and 226 Ra (25–900 Bq/kg). Apatite Ca 2 [(PO4) 3 (OH),F,Cl)], the predominant mineral, also contains trace amounts of 210 Po (
