DIRECTIONAL RADIATION DETECTOR

摘要

PROBLEM TO BE SOLVED: To enable to detect the position of a specified radiation and the movement state even if a detector is placed at a high radiation atmosphere. SOLUTION: Multiple radiation detector probes are distributed and placed in different directions to the exterior of a radiation shielding body, or multiple penetration holes are distributed and formed in different directions to the radiation shielding body with a shell shape, and the radiation detector probes are individually built into each penetration hole of the radiation shielding body. The radiation spherical or polygonal shielding body or a part of the exterior face of them is preferable. A position, a distribution, or a movement state of a radiation source can be detected by using these directional radiation detectors to calculate a position and a direction of each radiation detector probe and a measured value.
