Proportional counter tube

{
  "id": "MLC-T-CHM-009553",
  "term": "Proportional counter tube",
  "field": "Chemistry",
  "definition": "A radiation detector that measures ionizing radiation by collecting the ions produced in a gas-filled tube. The output pulse height is proportional to the energy deposited by the incident radiation, allowing for energy discrimination. This device operates in a voltage range where secondary ionization occurs but before the Geiger-Müller region.",
