PURPOSE:To enlarge visual field of image pick-up by dividing visual field of sample into several areas and by allowing each divided area to face one edge of image guide, where a scintillator has been buried at each sample side edge face, and connecting an image fuild-up tube to the other edge. CONSTITUTION:One edge of image guides 2a, 2b, 2c, and 2d is allowed to closely face a sample 1 to measure radiation which requires a wide visual field of for example 10cmX10cm. Detectors 3a, 3b, 3c, and 3d are connected to the other edge of the guides 2a-2d, respectively. And the detectors 3a-3d are connected to the monitor TV5 through an image processing unit 4. One edge of guides 2a-2d has an area of 50mmX50mm to face the position obtained by dividing the visual field of sample 1 into four areas and the other edge face has an area of 17mmX17mm to reduce the length by 1/3. It totally forms a truncated pyramid. In addition, a scintillator fine particle 8 is buried into the sample side edge face of guides 2a-2d. Thus, the image pick-up visual field can be enlarged.
