Abstract
A radiation-shielded injector comprises a cylinder of radiation shielding material having a cutout, a transparent radiation shielding plate being fitted to the cutout, a through-hole being provided at the closed end of the cylinder, a winged finger holding member being fixed to the cylinder, a cap having a hole for the passage through of a plunger being detachably attached, and a syringe-type body encapsulated with radioactive material, the cap being attached to the free end of the cylinder whereby the body is fixedly caught between the closed end of the cylinder and the cap. The infected is characterized by forming a built-up portion like a bank of radiation shielding material on the cutout periphery of the cylinder, the peripheral lateral side of the transparent plate being thereby covered with the thickness of the built-up portion. The radiation-shielded injector thus designed can minimize leakage of radiation and effectively protect the operator from radiation exposure.
