Abstract:
A method and apparatus for transporting radiopharmaceuticals. Typically, the apparatus is a two-part assembly, each part having an exterior shell, a radiation shield and a non-porous lining. Additionally, the assembled apparatus has a sealed internal chamber suitable for carrying a syringe or a sharps container containing a syringe. The internal chamber of the radiopharmaceutical pig is lined with a non-porous lining, typically a durable plastic, that prevents contamination of the radiopharmaceutical doses, the radiation shield, or the environment. Additionally, the non-porous lining can be quickly and easily cleaned and sterilized, avoiding the often difficult, to impossible, task of cleaning and sterilizing the radiation shield of the radiopharmaceutical pig. The non-porous lining is surrounded by a radiation shield that is typically comprised of elemental lead. The radiation shield prevents radiation from the radiopharmaceutical from contaminating the user or environment. The radiation shield is surrounded by an exterior shell that absorbs impact and prevents the radiopharmaceutical pig from breaking. Additionally, the exterior shell prevents environmental exposure to the potentially hazardous material of the radiation shield. Generally, a method of transporting a radiopharmaceutical by filling the container with a radiopharmaceutical, inserting the container into the internal chamber of the radiopharmaceutical pig having a non-porous lining, and assembling the radiopharmaceutical pig so the that the container is in the internal chamber and is encapsulated by the radiation shield, is also provided.

Abstract:
An improved drawing station system for handling radioactive material for use in syringes in the health care industry. The system includes a drawing station, a syringe shield and two different radiopharmaceutical pigs. The drawing station has a base with a support and two arms mounted thereto to support a first radiopharmaceutical pig enclosing a container of radioactive material. The radiopharmaceutical pig is releasably mounted to the second arm so that the radiopharmaceutical pig is pivotable about two predetermined axes to position the container for penetration by the syringe needle to draw radioactive material from the container into the syringe.
Abstract:
An improved radiation dense container for transporting radioactive iodine and the like, including a cup-shaped base having a cavity with an opening that is sized to receive radioactive iodine in the form of either one or more iodine capsules or a vial of iodine solution. The vial has a cap with a septum through which the radioactive iodine solution can be withdrawn from the vial in situ by an oral radioisotope administration set. A lid threadedly engages the base over the cavity opening to substantially seal it when threaded in place and to allow the insertion and removal of the radioactive iodine when removed. The base and the lid are both formed of tungsten. The container includes one or more activated charcoal filters to absorb any gases given off by the radioactive iodine when sealed in the cavity. An inner cup-shaped container and cap, made of plastic and sized and configured for a close fit within the base cavity, may be utilized to conveniently hold the capsules or, optionally, the vial.
