Title: Improved irradiation chamber
IPC: G01N23/04
Filed: 1966-07-22
Abstract: 1,108,709. Irradiation chamber. J. G. SCHNEEMAN. 29 July, 1966 [20 Oct., 1965], No. 34160/66. Heading H5R. An irradiation chamber has a surface on which specimens to be irradiated are placed, said surface being incorporated in a housing which encloses part of said surface and which supports a radiation source so as to be directed at the surface, said housing being fitted with a door which moves into and out of contact with the surface said door being pivoted so that on opening it functions as a shutter to stop the radiation beam reaching the surface and being shaped so that when open it renders the specimen arranged for irradiation, directly accessible from three sides. The edges of the door and the corresponding contact areas of the surface are adapted to provide a radiation seal around the enclosed area. Preferably, when fully open, the edge of the door defines 'a plane which intersects with the plane of the irradiation surface, and the door pivots about a line parallel to the line of intersection of these planes. A counterbalance may be connected to the door so as to bias the door into the open position. Preferably the irradiation surface is horizontal, the door is therefore mounted about a horizontal axis and the means to bias the door are adapted to be ineffective when the door engages said surface. A reflector may be mounted on the inside of the door so that when the door is open it cooperates with a light fitting mounted in the housing so as to reflect light on to the irradiating surface in the direction taken by the beam of opertive radiation so as to assist in positioning specimens. A conveyer means may be positioned so as to carry specimens on to and away from the irradiating area.
