Process irradiator

A process irradiator comprising a generally cylindrical shielded housing, an opening in said housing and a door movable to open and close said opening;

• a shielded storage cask;
• a source of radiation and a structure for moving said source between a shielded position in said storage cask and an irradiating position in the inside of said housing, said source of radiation being generally centered in said housing;
• a generally circular track positioned concentrically outwardly of said source;
• a carousel movable to a plurality of positions along said track around said source of radiation;
• and
• a plurality of turntables carried on said carousel and rotatable on their axes.

A process irradiator comprising a shielded housing having a floor, a wall, a top and an opening;

• shielding material, a shielded storage cask below said housing and a radiation source in said housing movable between a shielded position in said storage cask and an unshielded position within said housing, said radiation source comprising a plurality of source elements and a plurality of tubes containing and guiding said source elements;
• a perforated cylindrical member positioned concentrically around said tubes;
• a lifting structure for raising said source elements from said storage cask to the interior of said housing and returning said source elements to said storage cask;
• a generally circular track in said housing positioned concentrically outwardly of said source;
• a plurality of turntables movable to a plurality of positions along said track, said turntables being rotatable in position;
• a shielded door closing said opening and providing access when open to one of said turntables when said turntable is moved to a position adjacent said door;
• and
• containers carried on said turntables for containing material to be irradiated.

A process irradiator comprising a generally cylindrical shielded housing having an opening and a door for closing said opening;

• a shielded storage cask;
• a source of radiation generally centered in said housing and movable between said storage cask and an irradiating position in said housing;
• a circular track in said housing positioned concentrically outwardly of said source;
• a plurality of turntables and means for rotating said turntables on their axes;
• a carousel movable to a plurality of positions along said track carrying said turntables concentrically with respect to said irradiation source;
• and
• interlock controls which prevent said door from closing unless said carousel is rotated away from a door open position.
