Liquid Scintillation Counting | LSC Analysis - PerkinElmer

Liquid scintillation counting theory. Liquid scintillation counting (LSC) is the standard laboratory method to quantify the radioactivity of low energy radioisotopes, mostly beta-emitting and alpha-emitting isotopes. The sensitive LSC detection method requires specific cocktails to absorb the energy into detectable light pulses.
