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

Measurement of the scintillation time spectra and pulse-shape discrimination of low-energy beta and nuclear recoils in liquid argon with DEAP-1 [PDF]

, 2016
The DEAP-1 low-background liquid argon detector was used to measure scintillation pulse shapes of electron and nuclear recoil events and to demonstrate the feasibility of pulse-shape discrimination (PSD) down to an electron-equivalent energy of 20 keV.

Activity measurement of 55Fe using the liquid scintillation TDCR method

He 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.
