  "definition": "The counting rate obtained on a given instrument with a background counting sample. Typical reference background counting samples are: (1) Empty planchet: for G-M detectors, internal proportional counters, low background beta counters, alpha spectrometers. (2) Scintillation vial containing scintillant and sample known to contain no radioactivity: for liquid scintillation counters. (3) Container filled with distilled water: for gamma spectrometers.",
