Current approaches for assessing a confocal micro‐X‐rayfluorescence–probing volume involve the use of sharp knife edges, thin films, or wires, which are moved through this volume. The fluorescence radiation excited in the material of the object

Integration of transient signals is a commonly applied supervised approach to estimating isotope ratios from single-particle LA-ICP-MS measurements. Spectra collected on individual particles suffer from relatively weak signal strength and short durat

Detection of microscopic fission track (FT) star-shaped clusters, developed in a solid state nuclear track detector (SSNTD) by etching, created by fission fragments emitted from particles of fissile materials irradiated by neutrons, is a key techniqu

Free-living nematodes provide a good tool for environmental monitoring, because the nematode community structure is an appropriate bio-indicator. Soil-inhabiting species can be used for the characterization of soil functioning and heavy-metal polluti

This paper details an improved approach to environmental particle analysis for safeguards by means of a combination of an upgraded version of the so-called fission track method with state-of-the-art microscope and microprobe techniques. Improvements

Accumulation and distribution of uranium in roots and shoots of four plants species differing in their cation exchange capacity of roots (CECR) was investigated. After exposure in hydroponics for seven days to 100 μmol U L −1 , distribution of ura

A portable focused-beam X-ray fluorescence (XRF) spectrometer was designed and manufactured taking into account a huge variation in material, size and shape of museum objects. The spectrometer is equipped with a vacuum chamber enclosed with a Kapton-

Based on the design of the low cost Total Reflection X-Ray Fluorescence attachment module available since 1986 from Atominstitut (WOBRAUSCHEK-module) which can be attached to existing X-ray equipment, a new version was developed which allows the anal

The performance of x-ray capillary lenses has been evaluated. The tests were carried out using an x-ray tube set-up. A single glass capillary with tapered inner channel, a monolithic glass polycapillary, and an in-house manufactured single metallic c
