Preferred Label : proportional counter;
IUPAC definition : A gas-filled X-ray detector in which the electric potential is high enough for the
gain to reach a value in the range from 10E2 to 10E5. Each electron produced by the
initial photo-ionization causes one avalanche. Since the number of avalanche events
is proportional to the energy of the incident photons, the charge collected by the
anode is proportional to the X-ray photon energy.;
