  "term": "Counting efficiency",
  "field": "Chemistry",
  "definition": "The ratio of the number of detected radiation events (counts) to the actual number of radiation events emitted by a source within a given time period. It quantifies the effectiveness of a radiation detector in registering emitted radiation. This efficiency is influenced by factors such as detector geometry, energy of the radiation, and detector material properties, and is expressed as a fraction or percentage.",
