“…In order to overcome the problem in SIMS method, we developed a method to pick up individual particle containing U or fissile materials by micro-manipulation in SEM-EDX (scanning electron microscope-energy dispersive X-ray analysis) (see Figure 3 left). [14][15][16] For the FT-TIMS method, it is easy to observe FT by an optical microscope and to collect the particles separately (see Figure 3 right). [21][22][23] This method enables us to selectively detect highly enriched U particles, which is critical in the nuclear safeguards.…”

Japan Atomic Energy Agency (JAEA) has been conducting the environmental sample analysis, which is one of the IAEA's safeguards measures. In the analysis, isotope ratios of ultra-trace amounts of uranium and plutonium in samples taken from nuclear facilities are determined to detect undeclared nuclear materials and activities. In order to keep and enhance the reliability of the measurement results, validation of analytical methods and estimation of measurement uncertainty in such ultra-trace analysis should be properly done in accordance with worldwide standards. In this paper, the current activities on achievement of QA/QC (quality assurance and quality control) and estimation of measurement uncertainty in the ultra-trace analysis at a clean chemistry laboratory (CLEAR) of JAEA are reported.

“…The authors found that, for the samples collected in the church at the urban area, much of the K, Fe, and Zn appeared as mobile elements (exchangeable fraction), whereas for the church at the rural area, all elements were observed in all stages. A singleparticle transfer technique was developed and applied to TXRF by Esaka et al (187). A glass needle coated with gold was used for particle transfer.…”

In this review, we focus on the most significant and essential progress in X-ray spectrometry (XRS) published during the period 2006-2007 covering the following topics: developments and improvements in the detection performance and instrumentation of X-ray techniques and X-ray optics, new quantification models in X-ray spectra and data evaluation, micro-X-ray fluorescence (µ-XRF) including 3D-XRF, imaging techniques such as tomography and holography methods for 2D or 3D imaging of microstructures, electron probe microanalysis (EPMA), total reflection X-ray fluorescence (TXRF), particle-induced X-ray emission (PIXE) analysis, and X-ray absorption spectrometry (XAS). Finally, different applications in each subfield of XRS are described. Since the previous review, the sections of µ-XRF and 3D-XRF are newly introduced.An international group of scientists published two overviews on XRS (1, 2) in the Journal of Analytical Atomic Spectrometry covering the period 2006-2007 in the principal field of XRS analytical spectroscopic methods and instruments. These review articles involve all the important sections of XRS in nine chapters: reviews, instrumentation, spectrum analysis, matrix correction and calibration, X-ray optics and microfluorescence, synchrotron radiation, TXRF, portable and mobile X-ray fluorescence (XRF), and online XRF and applications. In the present review, we use a different method of classifying the information published in the literature during the 2006-2007 period: detection, instrumentation (except detectors) and optics, quantification models and related fundamental data, tomography and holography methods as primary tools of X-ray imaging, TXRF, EPMA, PIXE, XAS, and a final chapter that reviews the application of these methods in geology, environmental research, industry, biology, and medicine.Two practically useful books were published in 2006-2007. The handbook entitled Practical X-ray Fluorescence Analysis was edited by five famous German researchers (3). Following the historical progress of XRF, the basic and recent developments in X-ray sources, X-ray optics, and X-ray detectors are described. Quantification, specimen preparation, and special configurations, such as TXRF and micro-XRF, and their applications in environ-* To whom correspondence should be addressed.
