Radiosotope generator and method of construction thereof

摘要

A device for producing a fluid containing a radioactive constituent, comprising a shielded chamber ( 5 ) with an opening for receiving an isotope container ( 6 ) housing a radioactive isotope ( 7 ); a chamber closure ( 18 ) adapted for cooperating with and closing the chamber opening; a first fluid port comprising a first hollow needle projecting into the shielded chamber from the chamber closure for fluid communication with the isotope container; a second fluid port comprising a second hollow needle projecting into the shielded chamber from the closed end of the chamber opposite the chamber closure for fluid communication with the isotope container; first and second compressible buffers ( 28, 29 ) mounted so as to surround at least partially the respective first and second hollow needles ( 12, 13 ), each buffer providing an outer surface for contact with opposed ends of the isotope container; and a spacer of a predetermined thickness associated with one or each of the first and second compressible buffers for determining the positioning of the isotope container within the shielded chamber.
