In the early 1990’s there was a marked increase in the number of incidents where nuclear materials were found outside of regulatory control, including cases involving the illicit trafficking or possession of nuclear material. A new subdiscipline of nuclear science emerged out of the need to analyze these materials and use the characterization data to support both the prosecution of...
31. Identification of High Confidence Nuclear Forensic Signatures by Analysis of Spent Fuel Samples and Other Nuclear Materials
Dr É. Kovács-Széles (Hungary)
7/9/14, 9:20 AM
Nowadays, nuclear forensics has an increasing role worldwide. Several informative parameters have been already found for full characterization of nuclear materials with unknown origin for nuclear forensic purposes. However, international Round Robin exercises in the field resulted in that it is difficult to find exact and responsible parameters (signatures) for indisputable identification. For...
61. Detection and Distinguishing of Uranium Particles and Plutonium Particles by Using Alpha Autoradiography
Dr V. Stebelkov (Russian Federation)
7/9/14, 9:40 AM
The purpose of work is the development of the analytical procedure for the detection of rare uranium and plutonium microparticles on the surfaces of different objects and for determination, is the detected particle uranium or plutonium. Detection of uranium and plutonium particles and determination of the particle component: uranium or plutonium, are based on the results of analysis of the...
103. Development of a SIMS Method for Measurement of Oxygen Isotope in Nuclear Forensic Applications
Dr T. Wang (China)
7/9/14, 10:00 AM
Introduce: As a new branch of forensic science, nuclear forensics was developed with combination of nuclear radiochemistry and forensics. It aims to identify the origin, transfer path, process and purpose of the seized nuclear materials by analyzing their characteristic attributes. The main characteristic properties are dimensions, isotopic composition, impurities and microstructure, and so...

Processes conducted to extract uranium out of natural ore, recover uranium from leach solutions, and purify feed material for specific end uses are chemical in nature (1). These activities provide the opportunity for chemical reagents or reaction intermediates to carry over into uranium end-products. Measurements of chemical signatures provide information that is important to forensic...
