Nuclear forensics is the analysis of intercepted illicit nuclear or radioactive material and any associated material to provide evidence for nuclear attribution by determining origin, history, transit routes and purpose involving such material. Nuclear forensics activity includes sampling of the illicit material, analysis of the samples and evaluation of the attribution by comparing the analyzed data with database or numerical simulation. Because the nuclear forensics technologies specify the origin of the nuclear materials used illegal dealings or nuclear terrorism, it becomes possible to identify and indict offenders, hence to enhance deterrent effect against such terrorism. Worldwide network on nuclear forensics can contribute to strengthen global nuclear security regime. In this paper, the results of research and development of fundamental nuclear forensics technologies performed in Japan Atomic Energy Agency during the fiscal term of 2011-2013 were reported.

Development of an ultra compact device using liquid electrode plasma for radioactive element analysis

Commercial ICP AES is often applied for analysis of radioactive nuclides present in the waste stream. However, the instrument is bulky with auxiliary equipment. Consequently, it is difficult to maintain or replace those instruments in a shielded cell or a glove box. A novel liquid electrode plasma (LEP) would be a suitable option instead of ICP. LEP is compact to be easily installed, maintained and operated in a shielded cell or a glove box because the method does not require plasma gas, a nebulizer or large power supply. LEP allows only $$mu$$L-level waste emission due to the use of microchannel. In the study, we utilized LEP as an excitation source for analysis of radioactive nuclides. The newly installed instrument was characterized by determining cesium and strontium in a highly active waste simulated sample. The obtained result is promising for further application of LEP in the field of radiochemical analysis.
