Patent ID: 7495246

Claim:
A radiopharmaceutical pig comprising: A) a base comprising: i) a base shielding element comprising an open end, a closed end, and walls extending between the open end of the base shielding element and the closed end of the base shielding element, wherein the base shielding element consists of radiation-blocking material selected from the group consisting of lead, tungsten, and metallic-filled polymers; ii) a base shell comprising an inner base shell portion that is affixed to and lines completely an entirety of an interior of the base shielding element, wherein the base shell comprises a polymer material; and iii) a first hollow center section defined by the inner base shell portion of the base shell, wherein the first hollow center section is located between the walls of the base shielding element; and B) a cap removably attached to the base, the cap comprising: i) a cap shielding element comprising an open end, a closed end, and walls extending between the open end of the cap shielding element and the closed end of the cap shielding element, wherein the cap shielding element consists of radiation-blocking material selected from the group consisting of lead, tungsten, and metallic-filled polymers, the cap shielding element and the base shielding element being in overlapping relationship when the cap is attached to the base; ii) a cap shell comprising an inner cap shell portion that is affixed to and lines completely an entirety of an interior of the cap shielding element, wherein the cap shell comprises a polymer material, the inner base shell portion and the inner cap shell portion being in overlapping relationship when the cap is attached to the base; and iii) a second hollow center section defined by the inner cap shell portion of the cap shell, wherein the second hollow center section is located between the walls of the cap shielding element.
