Development of direct CO2 absorption system for radiocarbon dating and bio-based carbon determination in biogenic-synthetic products [PDF]

open access: yesNuclear Technology and Radiation Protection, 2022
This work presents a development of a new radiocarbon dating system based on CO2 and liquid scintillation counting. The system is flexible enough to be applied in different fields such as radiocarbon dating (up to about 32 000 years span ...

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

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.

Activity measurement of 55Fe using the liquid scintillation TDCR method

open access: yesHe jishu, 2023
Background55Fe is a low-energy radionuclide that is difficult to measure and decays to a ground state of 55Mn through pure electron capture (EC), accompanied by the emission of Auger electrons and low-energy X-ray.
