Research Abstract	Based on the previously developed two dimensional radiation imaging system with a grid structure, a three dimensional radiation imaging system has been developed. The grid is composed with aluminum alloy, which has been sintered in liquid scintillator. From the irradiation experiments with fast neutrons and gamma rays, it has been shown that this system could measure the distribution of the radiation induced energy deposition inside the liquid scintillator. We have also shown that the system could measure the average direction of incident radiation.
