Support housing for radioisotope generation

Housing for on-site radioactive parent-to-daughter isotope generation in which said parent radioisotope absorbed on an ion-exchange bed is selectively contacted with an eluting reagent to generate a short-lived daughter radioisotope, comprising:

• i. bottle means having mouth and a central repository defined by a side wall and a bottom wall,
• ii. a cylindrical column means positioned within said repository of said bottle means by attachment to said bottom wall of said bottle means, and including means attached at its interior suitable for support of said ion-exchange bed,
• iii. said column means also including a series of openings through its side wall adjacent to said bottom wall of said bottle means whereby said eluting reagent during initialization of the process can be conveyed from a position exterior of said column means but interior of the bottle means through said openings and thence into said interior of said column means in a batch flow pattern, to subsequently provide for radioative parent-to-daughter isotope generation at said ion-exchange bed interior of said column means.
