In a nuclear reactor institution, the neutron monitoring is indispensable in order to find an unusual neutron event which may be the signal of an accident or damage of a reactor. In this work, the possibility of a neutron monitor by means of an inorganic scintillator was researched. The detection efficiency and the intrinsic background of GSO scintillator and its sensitivity for neutrons have been studied.
