Abstract
An automatic radioisotope filling apparatus which includes a radioisotope vial containing a radioisotope solution, a saline vial containing a physiological saline solution and a plurality of label vials containing a drug into which a predetermined amount of the radioisotope solution or the physiological saline solution is to be filled automatically. A required amount of the radioisotope solution or the physiological saline solution is automatically metered and automatically filled into each label vial and consequently the radiation exposure of the operator of the apparatus is minimized.
