| Abstract: | Gamma-ray
spectrometric analysis is often considered as an ideal method for thorium
analysis, which would otherwise require the use of more tedious, time consuming
and often less precise chemical methods. With the development of rare earth
research, X-ray fluorescence spectrometry analysis has become an important
means of rare earth elements analysis and has been playing an increasingly
important role. In the present study, the XRF-spectrometry and
gamma-spectrometric techniques have been carried out in determining the
concentration of thorium in monazite bearing sand samples. Monazite is the
principal source of thorium and the rare earth elements but its composition and
the distribution may vary within very wide limits. Both XRF and Gamma-ray
spectrometry techniques use uncharged radiation, although of different in
origin, to identify and estimate concentrations of elements present in the
sample. However, the XRF method is much quicker and the amount of sample needed
for analysis is much less compared to gamma spectrometry analysis. The correlation study of the results obtained by
these two methods was analysed and compared. |
