Sensitive area

  "id": "MLC-T-CHM-013545",
  "term": "Sensitive area",
  "field": "Chemistry",
  "definition": "The specific portion of a radiation detector that responds to incident radiation and contributes to the output signal. This area is defined by the physical construction of the detector, such as the surface of a photodiode or the window of a photomultiplier tube. The response of the detector is not necessarily uniform across this entire area, and its effective size can be smaller than its physical dimensions.",
