The Problem of Interference in Neutron Activation Analysis,
Abstract
Interference in emission spectrography refers to the difficulty in the identification of a spectrum line of a given element from that of another element. In neutron activation analysis two possible cases may occur: either the interfering radionuclide is identical with the radionuclide liberated by the reaction, or it is an isotope or isomer of another element. In this second case the presence of the interfering nuclide may not be objectionable, and be detected by radiochemical control of the isolated substance. 3 interference groups are described: primary interference where the interfering nuclide is liberated by the reaction of the nuclei with the activated neutrons; secondary where a neutron displaces a proton from the nucleus and this particle then activates another nucleus thereby producing an interfering radionuclide and finally the interference caused by natural radioactivity.
