Abstract
An alpha-ray radiation source photographing device comprising a glove box having an optical window formed in a part of a wall thereof, alpha-ray radiation scintillator, on which an alpha-ray radiation source-containing sample is placed, disposed within the glove box and adjacent to the optical window, and photographing mechanism which includes an optical multiplier tube, a close-up lens system and a camera and is disposed outside the glove box such as to oppose the scintillator. According to this photographing device, the postion of the alpha-ray radiation source can be photographed from the outside of the glove box without inserting a film therein.
Claims6
An alpha-ray radiation source photographing device comprising a glove box, an optical window formed in a part of a wall of said glove box, an alpha-ray radiation scintillator, on which an alpha-ray radiation source-containing sample is placed, disposed within said glove box and adjacent to said optical window, and a photographing mechanism disposed outside said glove box such as to oppose said scintillator, said photographing mechanism including an optical multiplier tube, a close-up lens system and a camera, whereby alpha-ray radiation from said sample impinges upon said scintillator to emit light, and the emitted light advances through said optical window to the outside of said glove box and is amplified by said optical multiplier tube and photographed by said camera via said close-up lens system.
