METHOD FOR PREPARING STANDARD SOLUTION USING NEUTRON ACTIVE ANALYSIS

摘要

PURPOSE: A standard solution preparing method is provided to enhance the reliability of a standard solution by metering the trace elements of a primer through the neutron active analysis. CONSTITUTION: In the neutron active analysis, an artificial radioactive nuclide is generated from a stable element for the qualitative and quantitative analysis. A radioactive nuclide is generated by irradiating a neutron beam causing nuclear reaction with an atomic nucleus to a sample. The radioactive nuclide is changed to a novel stable nucleus by passing through a decay process corresponding to the inherent half period of respective nuclides while emitting a gamma ray of a specific energy. The qualitative analysis is possible according to the detection of a half period through repeated measurement of the energy of the gamma rays. Therefore, the neutron active analysis is proper to the analysis of the trace elements of a primer. Further, an absolute quantization without need of a standard material is possible.
