1. A gamma ray probe capable of being inserted into the human body, the gamma ray probe comprising:
a collimator;
a scintillator array disposed on a rear of the collimator and configured to emit light photons in response to radiation passing through the collimator;
a light sensor module disposed on a rear of the scintillator array and configured to detect light photons emitted from the scintillator array and convert the light photons into an electrical signal;
a light guide part disposed between the scintillator array and the light sensor module and configured to guide light photons from the scintillator array to the light sensor module; and
a cylindrical probe casing accommodating the collimator, the scintillator array, the light sensor module, and the light guide part therein,
wherein the light guide part is made of a material that reacts to radiation and emits light photons, with the material having a characteristic different from a radiation response characteristic of the scintillator array.
