A reagent feeder which can to be used in both a finger-push system and a slide system by only attaching and detaching a simple auxiliary component to and from a case body depending on the state of operation or a preference of the operator. The feeder includes a case body, a sphere discharge port and a discharge device, so as to discharge a sphere one by one by pushing down the discharge device. The discharge device is provided with an operation lever which extends out of the case body and can be pushed down by a finger. A slide cover surrounding an outer periphery of the case body is attached to the case body in such a way that it can be moved freely in a vertical direction and can be detached from the case body. The slide cover is engaged with the operation lever of the discharge device so that it can be moved integrally with the discharge device.

A double-sided needle assembly includes an insert needle for inserting into a vessel; an afflux needle for supplying pharmaceutical liquid in an injector to the insert needle; and a luer member. The member connects the insert needle with the afflux needle through a space defined between the ends of the needles in the member, and holds the insert and afflux needles to fit to the syringe of the injector under pressure. The confirmation of the insertion of the insert needle into the vessel is accomplished by observing the space of the luer member.

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.

Radiation-shielded holder for an injector

A radiation-shielding container comprising an outer plastic tube, an inner radiation-shielding metal tube inserted into the outer tube and a top plastic cap accompanied with a plug made of a radiation-shielding metal on its back and a bottom plastic cap, wherein the top and the bottom caps attach to the uppermost and the lowermost edges, respectively of the plastic outer tube in a snap-on method or a screwed or threading method, have respectively a peripheral thin section on the curved surface and are so designed that they can not be removed from the outer tube unless the thin section of the cap is cut off or that the thin section is forcibly opened.

A method for production of a thallium-carrying target material comprising a thermo-conductive support and metallic thallium electro-plated thereon, which comprises applying a DC-AC overlapped electric current between an anode made of a metal or its alloy having a lower ionization tendency than hydrogen and the electro-conductive support as a cathode, both electrodes being immersed in a bath of an electro-plating solution comprising monovalent thallium ions in the presence of at least one of aromatic amines and phenols, so as to deposit the thallium metal on the surface of the thermo-conductive support.
