the main detector of a scintillation counter depends on the calculating factor that you depict on using in your scintillation.

with one of several types of radiac: Geiger Counter, Scintillation Counter, Ionization Chamber, Electroscope, etc.
Scintillation counter
Neutrons from fission have a natural energy of about 2 Mev. In a thermal reactor these are slowed to thermal equilibrium by a moderator, at about 0.025 ev. At these lower energies (= slower speeds) we have more time to have them react with a measuring device, commonly a particle detector. Or a scintillation detector with associated light detector..

The Scintillation Counter uses a gas-filled metal tube.The Geiger Counter uses a phosphor-coated surface.

In the beta-counter or liquid scintillation counter, the sample is dissolved in an organic scintillation solution. Due to the resulting 100% counting geometry and the absence of any detector window, this means that the counter has excellent properties in detecting radionuclides of low activity emitting low energy beta-particles, such as H3 and C14. The light photons from the sample are collected by two photomultipliers in coincidence. This arrangement will reduce the background due to thermal noise and only true scintillation events will be analysed and counted. The main problem in liquid scintillation counting is the varying counting efficiency due to quenching of scintillation events. This process is caused by chemical contamination of the sample and/or a coloured sample. This means that the counting efficiency has to be determined for every sample. Therefore a quality control of the instrument must include a control of the correction methods. Otherwise the QC methods will be the same as for any scintillation counter. The sources needed for QC of a liquid scintillation counter include calibrated sources of H3 and C14 with different counting efficiencies as well as a background sample.
There are good alpha and beta scintillation counters but the geiger counter is usually preferred and is highly reliable. It serves as a portable general purpose alpha, beta, and gamma detector.
A Geiger counter usually has two detectors, especially in a two-piece bench type. The main detector is usually an ionizable gas in a metal tube.
A radiac detects nuclear radiation. There are many types of radiac, some are: Geiger counter, ionization survey meter, scintillation counter, film badge dosimeter, electroscope dosimeter, electrometer, drift meter, cloud chambers, etc.
