Scintillation detector The primary detector for radiation used by the RADEAGLET is the scintillation
detector. The scintillation detector consists of a crystal coupled to a photomultiplier. Once radiation
passes through the scintillation crystal, atoms of the crystal material become excited to higher
energetic levels. Once they fall back onto lower energy levels, they emit light. This light is very weak
and a source of light amplification is needed to see it. A photomultiplier is such an amplifier and it
allows us to observe the light emitted inside the crystal. Additionally, the light also tells us which
energy the incident radiation had. Analyzing the photopeak energies of the peaks in the spectrum
with the RADEAGLET’s advanced algorithms provides the list of radionuclides measured.
