  "id": "MLC-T-CHM-004789",
  "term": "Geiger counter",
  "field": "Chemistry",
  "definition": "A radiation detection instrument that measures ionizing radiation, such as alpha, beta, or gamma particles, by detecting the ionization produced in a gas-filled tube. When radiation enters the tube, it ionizes the gas, creating a cascade of electrons that results in a detectable electrical pulse. This device is commonly used for general radiation monitoring and contamination surveys.",
