A new method for D2O to H2O leak detection and identification of leaky heat exchanger in PHWR by Cerenkov photon counting technique [PDF]

open access: yesNuclear Technology and Radiation Protection, 2018
In pressurized heavy water reactors, leaks from D2O primary coolant and moderator to H2O secondary coolant and other light-water systems in heat exchangers cannot be completely ruled out.

Characterization of the scintillation response of water-based liquid scintillator to alpha particles, and implications for particle identification

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
Next-generation large-scale neutrino detectors, from Eos, at the 1 t scale, to Theia, at the 10 s-of-kt scale, will utilize differences in both the scintillation and Cherenkov light emission for different particle species to perform background rejection.

Enrichment of Low-Level Tritium in Groundwater via an Electrolysis Process for Liquid Scintillation Counting Applications

open access: yesGeosciences, 2023
Tritium levels in the groundwater of arid regions are very low; in most cases, these low tritium levels cannot be detected using a conventional liquid scintillation counter (LSC).

Measurements of angle-resolved reflectivity of PTFE in liquid xenon with IBEX

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
Liquid xenon particle detectors rely on excellent light collection efficiency for their performance. This depends on the high reflectivity of polytetrafluoroethylene (PTFE) at the xenon scintillation wavelength of 178 nm, but the angular dependence of ...

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

open access: yesFushe 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
