Several neutron detector designs exist. The

for its size. It is similar in size to the Geiger-Müller tube, but it utilizes

in limited supply. Due to this limited supply, the gas prices have risen and it became

much more expensive in the past years.

Scintillation detector The primary detector for radiation used by the radEAGLET-R is the

scintillation detector. The scintillation detector consists of a crystal coupled to a pho-

tomultiplier. Once radiation passes through the scintillation crystal, atoms of the crys-

tal 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 spec-

trum with the radEAGLET-R's advanced algorithms provides the list of radionuclides

measured.
