Patent Images
1. A radioactive dose dispensing apparatus for automatically filling a container with a required radioactive dose in a sterile environment, comprising:
- a container for containing a radioactive dose;
means for radiation shielding of said radioactive dose dispensing apparatus;
means for controlling a mix of radioactive stock solution and dilution stock solution for automatically diluting the radioactive stock solution with the dilution stock solution as both the radioactive stock solution and the dilution stock solution simultaneously pass into said container;
means for detecting radioactivity of said mix of radioactive stock solution and dilution stock solution; and
,means for automating said radioactive dose dispensing apparatus and calculating a required dose for controlling the radioactive dose being dispensed into said container, said means for automating said radioactive dose dispensing apparatus and calculating a required dose comprising a programmable logic controller operable in combination with a radiation detector.

Abstract
An apparatus and method for automatically dispensing a radioactive dose by filling a container, such as a vial or disposable syringe, with a required radioactive dose in a sterile environment; the apparatus being stand alone and radioactive-shielded. The apparatus further includes a control device for accurately dispensing and diluting the required radioactive dose using an online radioactivity measurement, which does not require knowledge of the volumetric radioactivity of the stock solution.
