介绍一种工业射线数字成像 (DR)检测系统。该系统用60 钴为γ射线源 ,被检工件放置在拖动平台上 ,垂直匀速穿过射线扇形面。由气体阵列电离室探测透射γ射线 ,信号经计算机处理 ,形成工件的二维透视图像 ,从而检测工件内部缺陷。该系统射线穿透本领大、图像质量及综合检测性能优良、运行维护费用低、占地面积小、操作简便、安全可靠 ,具有广阔的应用前景。
An industrial radiography digital imaging (DR) detection system is introduced. The system uses 60 cobalt as a gamma ray source, and the workpiece under inspection is placed on a dragging platform and vertically and uniformly passes through a ray fan surface. Detected by gas array ionization chamber transmission γ-ray, the signal processed by computer to form a two-dimensional perspective image of the workpiece to detect internal defects in the workpiece. The system has the advantages of large radiation penetration, good image quality and comprehensive detection performance, low operation and maintenance cost, small area, simple operation, safety and reliability and broad application prospect.
