Liquid scintillation counting (LSC) has its primary application in the counting of weak beta emitters, such as tritium and carbon-14. However, many other radioactive isotopes can also be measured, sometimes with higher counting efficiency and greater ease than by other techniques. Higher energy beta emitters can be readily counted as well as alpha and gamma emitters. Many organizations possessing an LSC spectrometer are unaware of the broad possibilities for use of LSC in studies with diverse radioelements, including many not usually considered in biochemical applications.
