PURPOSE:To easily search for the radiant ray source, by providing a radiant ray camera measuring and recording the relation of position of a radiant ray source, the intensity of radiant rays, and an optical camera to correspond the measuring point picking up a measuring region and recorded with the radiant ray camera to the radiant ray source in an actual plant. CONSTITUTION:A radiant ray camera consists of a cassette 1 holding a radiant ray sensing material such as atomic nuclear film and radiant ray film mainly and a collimator 2 having a lot of radial holes, and normal X-ray cassette can be used for the cassette 1, and the collimator 2 consists of a cassette containing section 3 accommodating the cassette 1 made of metal and a collimator fin 5 forming a lot of holes 4 extended radially in matching with the pickup region of the optical camera, and the fin is formed with casting of tin/lead alloy. The cassette containing section 3 is provided with a pack shield 6 commonly used as a cover and a press metal 7 and a pan head 8 and tripod 9 for the optical camera are used as a stand directing the radiant ray camera in the arbitrary direction. |
