Absolute photopeak efficiency

  "id": "MLC-T-CHM-000057",
  "term": "Absolute photopeak efficiency",
  "field": "Chemistry",
  "definition": "The probability that a gamma-ray photon emitted by a source will interact with a detector and deposit its full energy, resulting in a count within the photopeak. This efficiency is a function of the gamma-ray energy, detector size, and source-detector geometry. It is a key parameter for quantitative analysis in gamma-ray spectrometry.",
