  "term": "Absolute counting efficiency",
  "field": "Chemistry",
  "definition": "The ratio of the number of detected events to the total number of disintegration events occurring in a radioactive source within a specified time interval. This efficiency accounts for all losses due to detector geometry, absorption, and intrinsic detector response. It is a dimensionless quantity, often expressed as a percentage.",
