Liquid scintillation counting at the limit of detection in biogeosciences [PDF]

Frontiers in Microbiology, 2023
Liquid scintillation is widely used to quantify the activity of radioisotopes. We present an overview of the technique and its application to biogeosciences, particularly for turnover rate measurements.

Comparison of the efficacy of biodegradable and non-biodegradable scintillation liquids on the counting of tritium- and [14C]-labeled compounds [PDF]

Brazilian Journal of Medical and Biological Research, 2003
The widespread use of ³H and 14C in research has generated a large volume of waste mixed with scintillation liquid, requiring an effective control and appropriate storage of liquid radioactive waste.

Scattering-free lanthanide-ionic liquid scintillators for high-resolution and adaptive X-ray imaging [PDF]

Nature Communications
X-ray imaging requires effective light transmission through scintillation screens. However, solid or solution-based scintillators suffer from photon scattering and attenuation. While prior efforts have focused on improving light extraction in solid-state

Preparation of Large Volume Solid Argon Crystal and Its Feasibility Test as a Scintillation Material

Crystals, 2022
An important background to the liquid argon detectors is that they are caused by the diffusion of radioactive isotopes in a scintillator (liquid phase).

Measurements of Dispersed Phase Velocity in Two-Phase Flows in Pipelines Using Gamma-Absorption Technique and Phase of the Cross-Spectral Density Function

Energies, 2022
This paper concerns the application of the gamma radiation absorption method in the measurements of dispersed phase velocity in two-phase flows: liquid–gas flow in a horizontal pipeline and liquid–solid particles in a vertical pipe.

The liquid-argon scintillation pulseshape in DEAP-3600

European Physical Journal C: Particles and Fields, 2020
DEAP-3600 is a liquid-argon scintillation detector looking for dark matter. Scintillation events in the liquid argon (LAr) are registered by 255 photomultiplier tubes (PMTs), and pulseshape discrimination (PSD) is used to suppress electromagnetic ...
