A personal radiation protection garment that substantially contours to an operator's body is suspended from a suspension means. The garment is operable to protect the operator from radiation. The suspension means is operable to apply constant force. The suspension means allows operator wearing protective radiation garment to move freely in the X, Y, and Z spatial planes simultaneously, such that the protective radiation garment is substantially weightless to operator. A radiation protection face shield and flap can also be suspended from suspension means, such that face shield and flap are substantially weightless to operator. The suspension means can be mounted to a ceiling.

Compositions and processes for forming radiopaque polymeric articles are disclosed. In one embodiment, radiation inspection apparatuses and methods are then used to determine the presence and attributes of such radiopaque polymeric articles. A radiopaque polymeric article of the present invention can be created by mixing a radiopaque material, such as barium, bismuth, tungsten or their compounds, with a powdered polymer, pelletized polymer or liquid solution, emulsion or suspension of a polymer in solvent or water. In addition to creating radiation detectable objects, the radiopaque polymeric materials of the present invention can be used to create radiation protective articles, such as radiation protective garments and bomb containment vessels. Enhanced radiation protection can also be achieved through the use of nano-materials. The principals of the present invention can be used to provide protection against other types of hazards, including fire, chemical, biological and projectile hazards.

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.
