Liquid Scintillation Analyser
This instrument is used to measure the activity of low energy beta emitters such as H-3. P-32 and S-35 in biological samples for internal dosimetry of radiation workers. Urine sample, for example, is introduced directly into the organic scintillator that emits the photon light when interacting with beta radiation. The intensity of detected photon light enables quantitative determination of the radionuclide in the sample.
