Rapid Non-destructive Analysis of Chlorine by Neutron Activation


IT is known that 1.0-sec chlorine-38m is formed by neutron irradiation of natural chlorine and that it emits 0.66-MeV γ-ray. So it seems that chlorine can be determined by short-time irradiation with neutrons followed by γ-ray spectrometry. Since the half-life appeared to be too short to bring about precise determinations, we tried at first to observe the precision of the use of ten samples of ammonium chloride, 150 mg each.
