Liquid scintillation spectrometry in environmental measurements

Synthesis of plastic scintillation microspheres: Evaluation of scintillators

“…However, considerable differences are observed for weak beta emitters (e.g. 3 H) and alpha emitters (when microspheres of high diameter are used) since the particles lose energy in the aqueous phase before reaching the scintillator [12].…”

“…Liquid scintillation counting (LSC) [1,2] is the most often used technique for the measurement of beta and alpha emitters in environmental samples [3] and in highly active samples [4] that are produced by nuclear power plants, in research centres, or in hospitals. LSC is a simple and very well established technique; however, the use of LSC in some specific applications such as continuous measurements or measuring of samples with high salinity is problematic.…”

Survey on the presence of90Sr in milk samples by a validated ultra low level liquid scintillation counting (LSC) method

“…No self absorption occurs as a consequence of the homogeneous distribution of the sample in the scintillation cocktail [Schönhofer, 1995].…”

Crosslinked plastic scintillators: A new detection system for radioactivity measurement in organic and aggressive media

“…LS is a consolidated and robust technique for the analysis of aqueous samples with a high detection efficiency. However, LS exhibits some challenges when it is applied to the measurement of strong salt matrices due to phase separation, strong acid media due to luminescence, or strong oxidative media due to the degradation of the scintillator cocktail [1,7,8].…”
