1,088,518. Irradiating apparatus. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. April 19, 1966 [April 26, 1965], No. 17562/65. Heading H5R. An apparatus for irradiating cylindrical articles, e.g. with gamma rays, comprises a vertical member 1 located within the field of radiation with a guide structure 2 surrounding the member so as to form with the member a helical pathway 3, and means for rotating the member relative to the guide structure whereby an article 7 is rolled around the vertical member and along the passage way. In the preferred embodiment illustrated, the guide structure comprises a curved track having rails 4 and 5 supported on a framework 6, rail 5 serving to support the article and rail 4 serving as a radial restraint. Preferably the member 1 is hollow and surrounds the radiation source. The vertical member may be supplied with radially projecting guide elements 10 arranged helically around it and comprising a plurality of small rollers 11. A number of vertical members 1 and associated trackways may be assembled around a multiplicity of radioactive sources (Fig. 3, not shown). |
