Abstract

scintillation and Fluorescence

There are two methods commonly employed for the measurement of radiation: the ionization chambers, such as the various types of Geiger­Mliller tubes, and the scintillation counters.

The scintillation process involves the emission of discrete light flashes when a substance called phosphor or scintillator is struck by radioactive or other energetic particles. In fact, the word scintillator, comes from the Latin scintilla which means spark. Scintillation is related to fluorescence. The emission spectra for the two phenomena are almost identical, the difference between the two processes lying mostly in the method of excitation. In the case of fluorescence the source of excitation energy is ultraviolet light, while in scintillation, the exciting energy comes from radioactive particles.
