Abstract


 

The prompt gamma neutron activation analysis (PGNAA) spectrometer at the thermal neutron beam No.2 of the Dalat research reactor has been utilized as a supplement to instrumental neutron activation analysis (INAA) method for elemental concentration analysis in various kinds of samples. In this experimental study, we have developed a linear correlation standard function between the count rate of the 478 keV gamma peak and the boron content in the measured sample for analysing the boron concentration in various kinds of environmental, biological, and geological samples. The overall standard deviation of this function is less than 2,3 %. The results of the experimental analysis of the boron content in the standard samples of liquid, geology, and plants indicated a good confirmation with the certified data. The experimental parameter for boron analytical sensitivity is S = 0,11757 cps/µg.
