Now I know you know this refers to gas proportional counters and liquid scintillation counters, but just before this, at the end of the third paragraph, you mentioned anticoincidence counters.

The radioactive samples and cocktail are placed in small transparent or translucent ( often glass or plastic ) vials that are loaded into an instrument known as a liquid scintillation counter.

TNU is specific to the inverse beta decay detection mechanism with protons . 1 TNU corresponds to 1 geoneutrino event recorded over a year-long fully efficient exposure of 10 32 free protons, which is approximately the number of free protons in a 1 kiloton liquid scintillation detector.

The other common technology used for measuring activity is liquid scintillation counting, which was invented in 1950, but which had to wait until the early 1960s, when efficient methods of benzene synthesis were developed, to become competitive with gas counting; after 1970 liquid counters became the more common technology choice for newly constructed dating laboratories.

Facilities include Far-IR Fourier Transform Infrared Spectrometer, Fluorimeter RF-5000, Impedance Spectrometer and Inductively Coupled Mass Spectrometer ( ICP-MS ), Alpha Spectrometer, Liquid Scintillation Counter, High Purity Germanium Detector, Neutron Counter ED-XRF, HPLC, SFC, Ion Chromatography, Gas Chromatography etc . Among various achievements of the Group, Radioisotope production for medicinal importance is the ongoing important projects and has societal impact.
