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.

Time-domain based evaluation of detection efficiency in liquid scintillation counting [PDF]

Scientific Reports, 2021
This work explores the distribution of time intervals between signals from the photomultiplier tubes (PMTs) of a liquid scintillation counting (LSC) system when a scintillation burst caused by an ionizing particle is detected. This distribution is termed

Pulse-Shape discrimination with the Counting Test Facility [PDF]

Nucl.Instrum.Meth.A584:98-113,2008, 2007
Pulse shape discrimination (PSD) is one of the most distinctive features of liquid scintillators. Since the introduction of the scintillation techniques in the field of particle detection, many studies have been carried out to characterize intrinsic ...

A flow-through method for scintillation counting of carbon-14 and tritium in gas-liquid chromatographic effluents

Journal of Lipid Research, 1962
A method for radioassay of gas-liquid chromatographic effluents by scintillation counting has been developed. A cartridge filled with anthracene crystals is used as a “flow-through” radiation detector. Upon leaving the column, the effluent is passed over

Method for determining 226Ra in water via liquid scintillation counting and its uncertainty evaluation

Fushe yanjiu yu fushe gongyi xuebao, 2023
An analytical method was developed for the rapid determination of 226Ra in water through liquid scintillation counting. The separation and purification of 226Ra from water were performed by co-precipitation using barium sulfate as the carrier; the direct
