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.

Simultaneous determination of gross alpha/beta activities in water by liquid scintillation counting and its applications in the environmental monitoring. [PDF]
Sci Rep, 2022 Based on the standards of ISO11704-2018 and ASTM D7283-17, a method for simultaneous determination of gross alpha and gross beta activity concentrations in water by liquid scintillation counting (LSC) was established, which can be applied to various ...

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 ...

Fast determination of indoor radon (222Rn) concentration using liquid scintillation counting. [PDF]
J Radioanal Nucl Chem, 2017 The indoor 222Rn radionuclide was directly absorbed in typical 20 ml glass scintillation vials by passing −3 dm3 of ambient air through 16 ml of water-immiscible non-volataile scintillation cocktail Ultima-Gold F for 10 min. The activity of radon and its

Prospects of charge signal analyses in liquid xenon TPCs with proportional scintillation in the liquid phase [PDF]
2022_JINST_17_P03027, 2021 As liquid xenon TPCs increase in target mass while pursuing the direct detection of WIMP dark matter, the technical challenges arising due to their size call for new solutions and open the discussion on alternative detector concepts. Proportional scintillation in liquid xenon allows for a single-phase design evading all problems related to the liquid ...

Optimization of a portable liquid scintillation counting device for determining 222Rn in water [PDF]
Radiation Measurements, 2018, 2018 The new EU Council Directive 2013/51/Euratom of 22 October 2013 introduced limits for the content of 222Rn in drinking water. Radon analysis in water requires a lengthy task of collection, storage, transport and subsequent measurement in a laboratory.
