Abstract
A kit for the administration of a radiopharmaceutical liquid composition has been developed, which includes a radiation-shielding injector accompanied with a syringe-type vial having a gasket therein, a seal cap and a plunger to be engaged with the gasket. The injector is made of a radiation-shielding tubular metal body covered with a plastic material having an exit at the bottom, the body being further provided with a lead glass window on its curved surface, a packing engaging the inside surface at one end of the body and a pair of wings having skid-proof ridges formed on at least one surface thereof, the wings being located at one end of the body. The body is so designed as to be shorter than the tubular portion of the syringe-type vial to be inserted therein, whereby the rear portion of the vial protrudes a little from the tubular body when the same is inserted into the body.
