Gamma rays emitted from unstable nuclei in the earth and cities are flying in urban spaces. They have various energies depending on the type of nuclei emitted.
Here, a scintillator that emits light with different intensities according to the deposited energy of the incoming gamma rays is presented. The signal obtained in combination with the optical sensor that detects the light emission is digitized each time it arrives, and processed by the FPGA.
The energy of gamma rays is classified into bands and expressed by LED and displayed in a voltage meter. An old Geiger-Muller counter for environmental monitoring, a (He-3 proportional counter) for nuclear facilities, recent micropattern gas detectors for radiography are also exhibited.

Gamma rays flying in spaces have various energies depending on the type of nuclei emitted. Using a scintillator that emits light with different intensities according to the deposited energy of the gamma rays, the system differentiates the energy of incoming gamma rays by color. An old Geiger-Muller counter for environmental monitoring, a traditional neutron counter (He-3 proportional counter) for nuclear facilities, recent micropattern gas detectors for radiography are also exhibited.
