Nuclear forensics

Definition

Nuclear forensics is the analysis of nuclear material and radioactive substances to determine their origin, history, and the circumstances surrounding their use. This field plays a crucial role in national security by providing insights into illicit trafficking of nuclear materials, supporting law enforcement in criminal investigations, and aiding in the response to nuclear terrorism. By utilizing various radiochemical techniques, experts can trace the pathways of nuclear materials back to their source, making this discipline vital in ensuring safety and security on a global scale.

5 Must Know Facts For Your Next Test
