中子照相是20世纪60年代兴起的一种射线照相无损检测技术。中子与常规X射线原理相类似，但在穿透物体时的吸收特性显著不同，因此两种照相技术在适用范围上有一定的互补关系。国外中子照相技术已在航空航天、生物、考古、电子等方面有成功应用，国内由于中子源资源不易获得，应用研究滞后。简要介绍了中子照相技术的原理和检测系统构成，其基本构成为中子源、准直器和像探测器。阐述了中子照相技术的发展过程及国内外发展现状，列举了中子照相技术目前的国外的主要标准和工程应用情况，最后从研制移动式中资源、开展工业应用研究，建立相关标准等方面对我国中子照相技术发展趋势进行了展望。

Neutron radiography is a method of radiographic NDT technology rising in the sixties of the 20th century. The absorption characteristics of matter for X-rays and neutrons differ drastically; the two techniques in general serve to complement one another. Neutron radiography has found many successful applications in aerospace, biology, archaeology, electronics etc. Because of lacking of appropriate neutron sources, there are limited applications of Neutron radiography in China. This paper briefly introduces the principle of neutron radiography and the configuration of the typical neutron radiographic system. The development of the technology itself, its applications in NDT and standards established are at present and discussed. Finally suggestions on development of accelerator neutron sources, research on industrial applications and establishment of testing standards are presented.
