Analysis of “environmental samples” which consists in dust collected with cotton clothes wiped by inspectors on surfaces inside declared nuclear facilities is a key tool for safeguards. Although two methods (fission tracks-TIMS and SIMS) are already used routinely to determine the isotopic composition of uranium particles, the laser ablation-inductively coupled plasma mass spectrometry...

The age of nuclear and some other radioactive materials can be determined undoubtedly by using ICP-MS techniques. But it can be correct if only one nuclear or another radioactive material is presented in analyzed sample and no isotope-chronograph presented in background particles in significant quantities.
For particle analysis, which can be implemented by using SIMS, these restrictions are...

The isotopic analysis of micrometer-size uranium bearing particles, released from nuclear facilities, has been proven to be an efficient tool for safeguard purposes. The French atomic energy agency has developed analytical techniques to detect traces of uranium in these micrometric particles. However, isotopic measurements are not always sufficient for identifying specifically some crucial...

Researchers at Savannah River National Laboratory (SRNL) and Oak Ridge National Laboratory (ORNL) have been developing a tamper resistant/tamper indicating aerosol contaminant extractor (TRI-ACE) to be used for unattended environmental sampling in support of safeguards applications. Environmental sampling has become a key component of International Atomic Energy Agency (IAEA) safeguards...

Technique for increasing the accuracy of energy probe microanalysis (EPMA) of particles is proposed. EPMA with scanning electron microscope (SEM) and energy dispersive x-ray spectrometer is reasonable express method to search and analyze microparticles of nuclear materials. Accuracy of elemental analysis of uranium microparticles could be low if results are calculated with pre-installed...

Researchers have found many applications for lasers. About two decades ago, scientists started using lasers as sample introduction instruments for mass spectrometry measurements. Similarly, lasers as micro-dissection tools have also been increasingly on demand in the fields of life sciences, materials science, forensics, etc. This presentation deals with the interception of these...

This paper explores two somewhat novel mass spectrometric analysis techniques to characterise nuclear safeguards materials. The first uses Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) to perform rapid elemental analyses of trace components in uranium-bearing particles. We demonstrate this approach by measuring trace elements in eight different samples containing uranium-bearing...
