Assessment of radiological hazards in the phosphate

2021-6-1  NORM natural radionuclides present in phosphate mining areas can induce to gamma radiation external and internal exposure, β and α particles released from U-238, Th-232 and their radioactive daughters as well as from K-40. Most of the radionuclides that appear in phosphate rocks belong to the U-238 and Th-232 natural series, and K-40.

EPA Abandons Major Radiation Cleanup in Florida,

2014-1-28  The scientists noted that past phosphate mining had created elevated concentrations of radium-226 in the area's soil. Radium produces gamma rays that can penetrate the body and increase the risk for a variety of cancers. Inhaling or ingesting the uranium byproduct can increase the risk of leukemia, lymphoma and bone cancer, specifically.
