Environmental sampling to detect trace nuclear signatures is key component of international nuclear treaty enforcement. Herein, we explored rapid chemical extraction methods coordinated with measurement systems to provide faster, simpler assay of low level uranium from environmental samples. A key problem with the existing analytical method for processing environmental surface samples is the requirement...
In February 2014, an energetic gas-producing chemical reaction occurred in remediated plutonium processing waste emplaced in the Waste Isolation Pilot Plant causing the drum’s seal to fail and release radioactive material into and outside of the plant. This article provides results of our probative study using simultaneous thermogravimetric and differential thermal analysis and accelerating rate calorimetry...
The development of an alternative dispersive liquid–liquid microextraction protocol utilizing a low‐density extraction solvent, toluene, is described here for the extraction of the brominated flame retardant, tetrabromobisphenol‐A, from dust prior to selected ion monitoring analysis by gas chromatography with mass spectrometry. Method parameters of dispersive solvent type and extraction solvent type...
