A BRIEF INTRODUCTION TO NUCLEAR ANALYSIS TECHNICS
Analysis technics is often considered the eye of science. And the nuclear analysis technics is the keen eye of science and technology. Its fundamental principle is, by exerting high- energy particles on certain substance, to make the nucleus undergo minute changes. With the help of the said minute changes, the composition and structure of the matter are ascertained. Therefore, this technics is a concrete application of nucleus in
analysis.
The application of nuclear analysis technics in analyzing the various elements is characterized by high sensitivity, pre- cision, reliability, non-destructiveness and multi-element high-speed analysis. When applied in the research of material structure, this technics can not only analyze the static status of the substance, but also the kinetic microscopic structure thereof, which has no rival in other forms of analysis.
The nuclear analysis technics is roughly divided into: activiation analysis, ion-beam analysis, nuclear-physics effects, track display for solid matter, radio-isotopic fluorescent analysis, and the neutron scattering technology.
