Also called
single photon counting. The recording of sequential single photon pulses counted by way of recording the electron emission events from a photosensitive layer (photocathode) and multiplied by means of a '
dynode' arrangement (photomultiplier). This technique is used for two purposes: 1, the sensitive measurement of low levels of radiation; 2, the recording of emission decays.
