Multispectral large-area X-ray imaging enabled by stacked multilayer scintillators [PDF]

open access: yesarXiv, 2022
Conventional energy-integration black-white X-ray imaging lacks spectral information of X-ray photons. Although X-ray spectra (energy) can be distinguished by photon-counting technique typically with CdZnTe detectors, it is very challenging to be applied to large-area flat-panel X-ray imaging (FPXI).

Optimization of liquid scintillation measurements applied to smears and aqueous samples collected in industrial environments

open access: yesResults in Physics, 2016
Search for low-energy β contaminations in industrial environments requires using Liquid Scintillation Counting. This indirect measurement method supposes a fine control from sampling to measurement itself.

A comparative study of different radiometric methodologies for the determination of 226Ra in water

open access: yesNuclear Engineering and Technology, 2018
An evaluation of various radiometric methods to analyze 226Ra in water has been employed on a set of 10 standard solutions of different concentrations in the range of 1–10 Bq/L−1. The analysis was carried out using well-established procedures by means of

Rapid assay of labeled free fatty acids in mixtures of labeled lipids

open access: yesJournal of Lipid Research, 1968
The fatty acids in lipid mixtures are adsorbed on dehydrated hydroxy-charged ion exchange resin, the other lipids are removed by washing with solvent, and the adsorbed fatty acids are released with quaternary ammonium base for counting. All manipulations

Influence of natural radium contamination of barium chloride on the determination of radium isotopes in the water samples using α/β liquid scintillation spectrometry

open access: yesNukleonika, 2016
The determination of radium isotopes in drinking water by liquid scintillation technique requires some reagents that are used for separating radium from water samples. One of the main reagents is BaCl2·H2O.

Reconstruction of Point Events in Liquid-Scintillator Detectors Subjected to Total Reflection [PDF]

open access: yesarXiv, 2022
The outer water buffer is an economic option to shield the external radiative backgrounds for liquid-scintillator neutrino detectors. However, the consequential total reflection of scintillation light at the media boundary introduces extra complexity to the detector optics.

Combustion method for assay of biological materials labeled with carbon-14 or tritium, or double-labeled [PDF]

open access: yes, 1969
Dry catalytic combustion at high temperatures is used for assaying biological materials labeled carbon-14 and tritium, or double-labeled. A modified oxygen-flask technique is combined with standard vacuum-line techniques and includes convenience of ...
