The ITWG is an informal association of nuclear forensic practitioners, created in 1996 following a G-8 Summit in Ottawa, Canada. Today, with the participation of international experts representing more than 50 countries and multinational organizations, the ITWG has become the clearing house for developing and promoting nuclear forensic “best practices” worldwide. Many of these “best practices” are developed through the execution of Collaborative Materials Exercises (CMXs) that require participating laboratories to analyze special nuclear materials under realistic seizure scenarios. Past exercises have involved the nuclear forensic analysis of reactor and weapons grade plutonium fluorides and oxides and depleted, natural, low-enriched, and high-enriched uranium oxides and metals. Several exercises have also incorporated “traditional” forensic evidence requiring examination (e.g., fingerprints, tool markings, fibers) that were comingled or contaminated with radiological materials. The latest and largest of this exercise series, CMX-6, was completed in June of 2019 and included participating laboratories from 22 countries and multinational organizations and 15 law enforcement agencies. Highlights from CMX-6 will be presented, along with a summary of the current state-of-practice and emerging technologies in nuclear forensics as demonstrated over 20+ year history of CMXs.
