Abstract
Liquid scintillation counting makes use of an intimate mixture of radioactive sample and detecting medium which translates atomic radiation into light flashes. The light intensity of such a flash is proportional to the deposited energy in a burst of radiation, but the constant describing this proportionality may change from sample to sample because of chemical differences in various radioactive preparations. This chemical loss in detection efficiency is known as “quenching” and needs calibration if one is to get quantitatively meaningful results from liquid scintillation counting. Many ways are available for measuring quenching correction, and these have been reviewed by Peng [1].
