PROBLEM TO BE SOLVED: To discriminate a radiation (γ-ray) coming direction without applying particular processing to scintillator members in a radiation measuring device comprising a plurality of scintillator members.SOLUTION: A detection unit 10 is comprised of three detection probes 14, 16, 18 and a filter member 20. In the filter member 20, sensor portions (distal end portions) in the detection probes 14, 16, 18 are buried and inserted in positions which are different from each other, thereby generating horizontal direction orientation characteristics different from each other therein. Signal processing sections 22, 24, 26 measure three count values N1, N2, N3 and a main computing section 32 refers to a designated response function to discriminate a radiation coming direction from the three count values. At an upper side of the detection unit 10, a display section 40 may also be layered. |
