摘要： Disclosed is a method of discriminating materials by employing fast neutron and continuous spectral X-ray and an equipment for the same. The method comprising the steps of: (a) transmitting a fast neutron beam produced by a fast neutron source and a continuous spectral X-ray beam produced by a continuous spectral X-ray source through inspected objects; (b) directly measuring the intensity of the transmitted X-rays and the intensity of the transmitted neutrons by a X-ray detector array and a neutron detector array respectively; and (c) identifying the materials of the inspected object by Z-dependency curves formed by the attenuation differences between the neutron beam and X-ray beam transmitted through different materials of the inspected object. This direct measurement of transmitted dual-ray technique has much more efficient than secondary radiations measurement such as neutron activation analysis, has much more material discrimination sensitivity than dual-energy x-ray technique. The respective measurements of neutrons and x-rays make the usages of high detect efficiency neutron detectors and x-ray detectors possible. The using continuous spectral x-ray produced by Linac adds more advantages such as: high penetration ability, high spatial resolution, and high image quality over monoenergetic dual-ray technique.

摘要翻译： 本发明公开了一种采用快中子和连续光谱X射线鉴别材料的方法及其设备。 该方法包括以下步骤：（a）通过检测对象发射由快中子源产生的快中子束和由连续光谱X射线源产生的连续光谱X射线束; （b）分别通过X射线检测器阵列和中子检测器阵列直接测量透射的X射线的强度和发射的中子的强度; 和（c）通过由穿过检测对象的不同材料的中子束和X射线束之间的衰减差形成的Z依赖曲线识别被检物体的材料。 传输双光线技术的这种直接测量比二次辐射测量（例如中子活化分析）更有效，比双能X射线技术具有更多的材料辨别灵敏度。 中子和x射线的相应测量使得高检测效率的中子探测器和x射线探测器成为可能。 Linac生产的使用连续光谱X射线增加了更多的优点，如：单能量双光线技术，高穿透能力，高空间分辨率和高图像质量。
