Abstract

1,018,723. Irradiation apparatus. RONTGEN A.B. ISO-X. Oct. 29, 1962 [Nov. 8, 1961], No. 40810/62. Heading H5R. Radiographic examination of a body is made by use of radio-active I 125 which emits substantially monochromatic X-radiation of about 27 Kev. energy. The source is preferably not greater than a few sq. mms., e.g. 0À5 sq. mms. in area, and is preferably composed of silver iodide carried on a support of silver wire. The source may be produced by allowing gaseous or a solution of elementary radio-active 1125 to react chemically with the support, by electrolytically depositing 1125 from a solution in an organic solvent of low viscosity, e.g. acetone, or by the hetergeneous ion exchange between I 125 in solution and a crystal of a salt which is only slowly soluble in the solution. The source is mounted within a housing which is provided with a tubular shutter which slides over the source, or the source is mounted within a rotatable shielding mass, a Bowden cable being used to rotate the mass from a position of total shielding to a position of exposure.
