1. From ionizing radiation to light
A history of liquid scintillation measurement is given in Box 1.
The liquid scintillation activity measurement technique transforms the ionizing radiation produced by the decay or de-excitation of a radioactive atom into detectable and quantifiable light radiation. The technique is based on a cascade of energy transfer phases involving ionizing radiation, electrons, light photons and photomultiplier electrons. The overall efficiency of the phenomenon depends on the optimal coupling of all these processes.
1.1 Radiation-matter interaction
The decay or de-excitation of a radionuclide leads to the emission of energy in the form of radiation (Box 2). In liquid scintillation activity measurement practice, the radiation encountered is...
