Beta counter: Instrument for the detection of beta particles and hence quantification of beta-emitting radioactive material.

Beta particle (b): Electron emitted from an atomic nucleus during a nuclear decay in which the atomic number (Z) increases by 1 (essentially, a proton is converted to a neutron with emission of an electron from the nucleus).

Proportional counter: A gas-filled radiation detector in which electrons are accelerated towards an anode, creating secondary ionization events in the gas, which in turn cause additional ionization events, etc. This cascade (Townsend avalanche; charge amplification) results in electronic pulses which are proportional to the energy originally deposited within the detector by ionizing radiation.

Liquid scintillation counter: A liquid-filled radiation detector in which a radioactive sample is dissolved into a liquid scintillator (typically based on an organic solvent such as toluene). Deposition of energy through ionizing radiation...
