  "id": "MLC-T-MET-008340",
  "term": "Radioactive snow gauge",
  "field": "Meteorology and atmospheric science",
  "definition": "An instrument that measures the water equivalent of snowpack by detecting the attenuation of gamma radiation emitted from a radioactive source placed beneath the snow. The amount of radiation absorbed is inversely proportional to the snow depth and density. This method provides continuous, automated measurements of snow water equivalent.",
