| Abstract: | The possibilities of multielement neutron activation analysis of the mineral raw materials of the Socialist Republic of Vietnam, have been studied. Samples were activated by a252Cf neutron source (yield 4·109 n·s–1). The induced activity was measured by coaxial Ge(Li) and planar Ge detectors. The content of gold, thorium, uranium, rare earths and other elements, was determined and evaluated in ores and concentrates by an absolute method. |
