Nuclear Forensics: Tracing the Source of Isotopes

Nuclear forensics is the science of identifying where radioactive materials come from.
Scientists analyze isotopic “fingerprints” to trace uranium, plutonium, or other materials.
Each sample carries unique clues about its origin, processing, and history.
Techniques include mass spectrometry, gamma spectroscopy, and chemical analysis.
Forensics can determine if seized nuclear material came from a reactor or a weapon program.
It helps law enforcement stop nuclear smuggling and terrorism.
International agencies like the IAEA use forensics to monitor compliance with treaties.
Nuclear forensics also investigates past nuclear tests and accidents.
Data libraries of isotope signatures are key for rapid identification.
This field blends physics, chemistry, and detective work to keep the world safer.
