Such as ore contain natural radioactive nuclides at various concentrations. If this ore contain high concentrations of natural radioactive nuclides, workers handling them might be exposed to significant levels of radiation. Therefore it is important to determine the radioactive nuclides in this ore. Approach: The natural radionuclides (238U, 232Th and … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 7,024 accessesView PDFCite
