This invention relates to a radiation detection device for detecting ionizing beam discharges such as gamma rays, x-rays, electron beams, charged particle beams and neutral particle beams. Specifically, it relates to a radiation detection device which can measure radiations which exist for a very short time (of the order of subnanoseconds or less) from the appearance of photoemission to extinction.It is an object of this invention to provide a radiation detection device using a perovskite organic-inorganic hybrid compound as a scintillator, the formula of this compound being (R<1>-NR<11>3)2MX4 or (R<2>=NR<12>2)2MX4, or alternatively, (NR<13>3-R<3>-NR<13>3)MX4 or (NR<14>2=R<4>=NR<14>2)MX4 (in the formula, R<1 >is a monovalent hydrocarbon group which may contain a heterocyclic ring and may be substituted by halogen atoms, R<2 >is a divalent hydrocarbon group which may contain a heterocyclic ring and may be substituted by halogen atoms, and may be cyclic, R<3 >is a divalent hydrocarbon group which may contain a heterocyclic ring and may be substituted by halogen atoms, R<4 >is a tetravalent hydrocarbon group which may contain a heterocyclic ring and may be substituted by halogen atoms, R<11>-R<14 >may be identical or different, and may be hydrogen atoms or alkyl groups having two or more atoms, M is a Group IVa metal, Eu, Cd, Cu, Fe, Mn or Pd, and X is a halogen atom). This radiation detection device can quantify the radiation amount of the detected radiation.
