T. Akyuz et al., INVESTIGATION OF URANIUM AND THORIUM CONCENTRATIONS IN THE FLUORITE BEDS OF ANATOLIA BY USING SOLID-STATE NUCLEAR TRACK DETECTORS, Journal of radioanalytical and nuclear chemistry, 220(2), 1997, pp. 259-261
Uranium and thorium concentrations of fluorite samples taken from the
main fluorite beds of Anatolia (Turkey) have been determined by fissio
n fragment radiography using solid state nuclear track detectors (SSNT
Ds). The fissionable elements concentration of the fluorite samples we
re found to be 10(-4)-10(-7) g/g. The Th/U ratio, obtained for all the
fluorite samples, is found to be characteristic for the location of t
he samples. Some correlations between the concentration of Th and thos
e of lanthanites and concentration of U and that of Mo or Zr are obser
ved.
