Description
Neutron imaging is a powerful non-destructive technique that is particularly sensitive to light elements, such as hydrogen, due to the interaction of neutrons with atomic nuclei rather than electron clouds. This unique contrast mechanism enables the visualization of materials and processes that are often inaccessible using conventional X-ray imaging, making neutron imaging especially well-suited for in situ studies.
This presentation highlights two emerging applications of neutron imaging. The first focuses on paleontology, where neutron imaging is being used to investigate the preservation of soft tissues, including blood vessels, within fossilized dinosaur bones. The ability to visualize these structures within their original three-dimensional geometry provides new opportunities to study tissue preservation and fossilization processes.
The second application addresses crop optimization and plant science. Owing to its exceptional sensitivity to water, neutron imaging enables direct visualization of water uptake and transport within plant root systems and surrounding soils. These measurements provide valuable insights into plant-water interactions and drought responses, supporting efforts to develop more resilient agricultural systems.
Together, these examples demonstrate the versatility of neutron imaging as a tool for studying dynamic processes across a wide range of scientific disciplines.
