Az előadás angol nyelvű összefoglalója:
Detection and nuclear forensic analysis of confiscated nuclear and other radioactive materials at the Centre for Energy Research
Nowadays, terrorism shows increasing activity worldwide. Within this the nuclear terrorism, i.e. malicious use of radioactive materials, represents a special area. The International Atomic Energy Agency registered ~4000 cases connected to the unauthorized usage of radiological materials from the early ‘90s. Nuclear forensics is the examination of these materials using analytical techniques to determine the origin and history of the seized material in the context of criminal investigations or the assessment of nuclear security vulnerabilities. The aim of nuclear forensics is to help authorities to find responsible persons behind malicious use and to fight against the nuclear terrorism.
Nuclear forensics, as an official task, has been delegated to the Centre for Energy Research (EK) since 1996. The centre plays a significant role in assuring nuclear security in Hungary, in the Central European Region and internationally based on its more than four decades R&D activities in nuclear physics and chemistry. During the last 10 years nuclear forensics activities have been significantly expanded in Hungary. Many different techniques were integrated and used for this activity, like scanning electron microscopy, mass spectrometry, gamma-ray spectrometry and X-Ray techniques. Nuclear forensics requires a multidiscipline knowledge to determine the history and origin of the materials and to answer the questions of the investigator.
The presentation includes the introduction of nuclear forensics and its widespread detection and analytical tools for the analysis of radioactive and nuclear materials with unknown origin.
