Abstract
PURPOSE: To easily detect the radioactive contamination of each part of the human body, by constituting a gate monitor of a detector by which a scintillation detection surface has been formed on plural surfaces of a rectangular parallelepiped, a surface except the bottom surface of a cylinder and a square pipe, and a spherical surface except one part of a spherical shell.
CONSTITUTION: A scintillation detection surface is formed on a wide part of the outside surface of a rectangular parallelepiped, a cylindrical body, a spherical body, etc. For instance, a reflection surface 4 is formed on the inside surface of a rectangular parallelepiped vessel 11, and it is covered with a light shielding film 13 which has been formed so that a top surface 11a, and both side surfaces 11b, 11c are set to an opening surface 15, and the inside surface is made to a reflection surface. A plastic scintillator 12 having thickness of 1W2mm or so is placed so as to be opposed in the proximity of its inside. Two photoelectric multipliers 5 are provided so that its photoelectric surface 5a is opposed to the side surfaces 11b, 11c, in the proximity of a bottom surface 11d. In this regard, since the scintillator has been made thin, a light beam is absorbed little, light emission by the scintillator is not attenuated, and attains to the photoelectric surface 5a. When a gate monitor is constituted by placing a scintillation detector formed in this way, back and forth, and on the right and left, the radioactive contamination of each part of the human body is detected exactly.
