CETAMA Contribution to Safeguards and Nuclear Forensic Analysis based on Nuclear Reference Materials

Recent Advances in Nuclear Forensic Chemistry

“…There is a growing need within the nuclear forensic community for particulate uranium- and plutonium-based CRMs with a known isotopic composition, as most current CRMs for nuclear forensic applications are only available as bulk materials. ,− Without microanalytical control measurements on independently verified and standardized particulate materials, forensic analysis of seized nuclear materials could potentially be deemed inadmissible in certain courts. , Production of these standard materials relies upon the development of controllable synthetic routes, which are in turn dependent upon a mechanistic understanding of the formation processes. Within the past few years, a relatively large amount of progress in this realm has led to the discovery of new or substantially improved processes to synthesize these nanomaterials − and has also resulted in significant improvements for their characterization.…”

Thermal ionisation mass spectrometry (TIMS) in nuclear science and technology – a review

“…A book on nuclear forensics and several reviews and popular articles have appeared during the last couple of years on the growth and development of nuclear forensics. [116][117][118][119][120][121][122][123][124][125][126][127] TIMS is a unique analytical tool in nuclear forensics to nd out the origin of the interdicted material and the age of the material. [128][129][130][131][132][133][134][135][136][137][138][139] The latter means the time elapsed aer the latest purication of U and/or Pu.…”

An isotope dilution mass spectrometry overview: tips and applications for the measurement of radionuclides

“…The Commission for the Establishment of Analytical Methods (CETAMA) is a unit of the French Alternative Energies and Atomic Energy Commission (CEA), which has a goal of measurement quality improvement within the nuclear eld. 23,[55][56][57][58] The main activities of CETAMA are to develop and provide CRMs for nuclear analysis laboratories worldwide, to organize ILCs and to participate in the standardization of analytical methods. One of the CETAMA's working groups is dedicated to ID-MS which gathers several national and international scientic bodies (CEA, French Institute for Radiation Protection and Nuclear Safety (IRSN), Joint Research Centres (Europe), IAEA, Belgian Nuclear Research Centre (SCK)) that share their know-how in radionuclide analysis by ID-MS.…”
