我国非动力核技术工业应用仪器的发展过程与趋势

The Development Process and Tendency of Nuclear Instruments Applied in Industry

我国非动力核技术工业应用仪器始于20世纪50年代,依据其实际发展过程,可概括为三个阶段:以核子密度仪、厚度仪、料位计为代表的早期阶段;以中子水分仪、灰分仪、X荧光分析仪为代表的中期阶段;以集装箱检测成像装置与工业CT、核磁共振仪、中子瞬发γ多元(核)素分析技术为标志的近期阶段。我国非动力核技术工业应用仪器的发展趋势为:计数测量向测谱演变;阵列探测器与成像技术的广泛应用;核素与核素比分析方法的发展及新型核辐射探测器的应用。

The development process of nuclear technique application in industry may be divided into three stages: early stage——density, thickness and level measurement; middle stage——neutron moisture, ash content and X-ray fluorecence analysis; recent stage——container inspection and industrial CT, nuclear magnetic resonance, neutron capture and non-elastic collision analysis techniques. The development tendency of nuclear instruments applied in industry is: spectrum measurement; detector array and image technique; nuclide analysis and new kinds of nuclear detectors are widely adopted.
