RADIOACTIVE ISOTOPE GENERATOR OF SHORT-LIVED NUCLIDES

摘要

A radioactive isotope generator for conducting parent-daughter radio-nuclide separations and containing a relatively small amount of radioactivity, the generator comprising a container or column having a parent nuclide disposed therein, the parent nuclide being separated from the remainder of the column by a filter material. As a specific embodiment, the generator comprises a column having two chambers separated by a filter material, the parent activity being adsorbed on an adsorbent such as alumina and being disposed in one of the chambers as a suspension. The open end of the column proximate the empty chamber is sealed by a puncturable stopper. By evacuating the empty chamber by means of a syringe inserted through the puncturable stopper, for example, the solution containing the daughter nuclide will pass through the filter and into the empty chamber, from which it is available for use.
