Abstract
The disclosure of this application is directed to a protective shielding assembly suitable for use in the loading of a hypodermic syringe with radioactive material. The protective shielding device receives and securely holds, at one end, a vial which contains the material to be loaded and at its opposite end a hypodermic syringe with the needle of the syringe approximately centered with respect to the septum of the vial. Penetration of the septum of the vial is effected by moving the slidable members of the protective shielding assembly toward the vial which in turn moves the hypodermic syringe causing the needle of the hypodermic syringe to rupture the vial septum and enter the vial.
