The quantitative analysis of sixteen elements in normal human enamel and dentine by neutron activation analysis and high-resolution gamma-spectrometry

The sample to be analysed and a standard of known composition were irradiated simultaneously and the induced radioactivity compared. The investigation was done with high resolution Ge (Li) detectors coupled to fully transistorized 400 and 4000 channel analysers. By varying the irradiation time and conditions, it was possible to employ a non-destructive analytical procedure. The concentration of 16 elements, namely, Mg, Na, Cl, Al, Ca, Cr, Ba, Sb, Ag, Zn, Co, Fe, Sr, Au, Br and Mn was determined in normal human enamel and dentine by instrumental activation analysis. © 1971.
