neutronigrafia

Neutronigrafia is a term sometimes used to refer to neutron radiography or neutron imaging. This non-destructive testing technique uses neutrons as a source of radiation to penetrate materials and create an image, much like X-rays. However, neutrons interact with matter differently than X-rays. They are particularly effective at penetrating dense materials like lead and are sensitive to light elements like hydrogen, which are often difficult to image with X-rays.

The process involves directing a beam of neutrons through an object. As the neutrons pass through, they are attenuated to varying degrees depending on the material's composition and density. A detector placed on the opposite side records the intensity of the transmitted neutrons. This data is then processed to form an image, where variations in brightness correspond to differences in neutron attenuation.

Neutron radiography finds applications in various fields. It is used in industry for inspecting components in aerospace, automotive, and nuclear sectors, revealing internal defects or structural integrity. In archaeology, it can be used to examine artifacts without causing damage. Scientific research also utilizes neutron imaging for studying material properties, fluid flow, and biological samples. The ability to visualize internal structures, especially those composed of light elements or within dense materials, makes neutronigrafia a valuable complementary technique to other imaging methods.
