Abstract
The automatic radioisotope filling apparatus of the present invention is equipped with a radioisotope vial containing a radioisotope solution, a saline vial containing a physiological saline solution, a dilution vial to which a predetermined amount of the radioisotope solution and a predetermined amount of the physiological saline solution are to be transferred to prepare a diluted radioisotope solution, a radiation detector for measuring the radioactive intensity of the diluted radioisotope solution prepared in the dilution vial, and a plurality of label vials containing a drug to be labeled. With this apparatus, the radiation exposure which the operator undergoes can be reduced and a diluted radioisotope solution of precisely known radioactivity can be transferred to the label vials, by employing special methods in stirring the label vials, in sequentially transferring the diluted radioisotope solution to the label vials, and in transferring the radioisotope solution and the physiological saline solution to the dilution vial and the label vials.
