摘要：

A new computerised neutron activation technique permits rapid nondestructive simultaneous elemental and isotopic uranium analysis with various applications, such as nuclear material standardization and safeguards analysis. The technique consists of dual cyclic neutron activation in a differentiated neutron flux spectrum at bare and cadmium covered irradiation positions and subsequent delayed fission neutron counting. Calibration curve fitting by polynomial approximation and data processing by GRAPHER and LOTUS 123 software computer programs gave satisfactory results.
