Editing Liquid scintillation counting (section)

== Cherenkov counting ==
High-energy beta emitters, such as [[phosphorus-32]] and [[yttrium-90]] can also be counted in a scintillation counter without the cocktail, instead using an aqueous solution containing no scintillators. This technique, known as '''Cherenkov counting''', relies on [[Cherenkov radiation]] being detected directly by the photomultiplier tubes. Cherenkov counting benefits from the use of plastic vials which scatter the emitted light, increasing the potential for light to reach the photomultiplier tube.
