我将在此通过分享伦勃朗作品的检测分析实例,介绍中子放射自显影检测技术在保存修复中的应用方法。X射线摄影技术反映的是感光底片对放射光源发射出的X射线的吸收程度。使用中子放射自显影技术,并不需要放射光源透过研究对象,而是利用对象本身所产生的较低辐射率作为辐射物质进行的感光成像。其基本原理是通过中子原子反应堆对油画进行人为干扰,将一个额外的中子整合到了原子核之内,中子在减
Here, I will share examples of detection and analysis of Rembrandt’s work to introduce the application of neutron autoradiography in preservation and repair. X-ray photography reflects the degree of absorption of X-rays emitted from a radiation source by a photographic film. The use of neutron radiation autoradiography does not require radiation source through the study, but the use of the object itself produces lower emissivity as a radiation-sensitive material imaging. The basic principle is to make man-made interference with oil painting through the neutron atom reactor, integrating an extra neutron into the nucleus, reducing the neutron
