Natural radioactivity in phosphates, phosphogypsum and natural waters in Morocco

摘要

The contents of natural radionuclides (uranium, actinium and thorium series) were measured in sedimentary phosphate rock samples using high-resolution gamma spectrometry. Data obtained for uranium content (ppm) were compared with the results obtained by a Method based on the measurements using solid-state nuclear track detectors (SSNTD) in the Same samples. The potential leaching of radionuclides from sedimentary phosphate rock During the industrial production of the phosphoric acid was studied.
