Abstract: Radiation shields and radiation shielding systems for attenuating ionizing radiation include two or more attenuating elements, such as layers. The two or more attenuating elements may include different attenuating materials. The two or more attenuating elements may be configured to attenuate ionizing radiation differently than one another. In some embodiments, different attenuating elements may be configured for use with different energies or ranges of energies of ionizing radiation. The concurrent use of two or more layers or other attenuating elements may optimize the ability of a radiation shield to attenuating ionizing radiation. Systems and methods for attenuating ionizing radiation are also disclosed.

Abstract: Apparatuses, systems and methods for tracking medical equipment, or one or more medical devices, such as radio-opaque shields, are disclosed. Use of the medical device(s) may be tracked. Withdrawal of the medical device(s) from service for maintenance, other service and/or validation may be tracked. When a tracked medical device comprises a radio-opaque shield, the cumulative exposure of the medical device or an individual or object shielded by the medical device to ionizing radiation may be tracked, as may the cumulative amount of ionizing radiation attenuated by the medical device. Methods for actively or passively tracking one or more medical devices until the arrival of a time for a predetermined, or scheduled, event are also disclosed, as are methods for performing predetermined events.

Abstract: Apparatuses, systems and methods for tracking and providing reminders of scheduled events for medical equipment involve the use of portable tracking devices that may be secured to individual items of medical equipment that are scheduled to which one or more scheduled events may apply. In a specific embodiment, shields for limiting an individual's exposure to ionizing radiation may be tracked. Methods for actively or passively tracking one or more medical devices until the arrival of a time for a predetermined, or scheduled, event or total time elapsed are also disclosed, as are methods for performing predetermined events on medical devices.

Abstract: Shields that attenuate ionizing radiation (e.g., x-rays, gamma rays, etc.) include outer layers that minimize soiling. Removable shells that minimize soiling of shields for attenuating ionizing radiation are also disclosed. The soil-minimizing outer layers and shells may be formed from materials that resist soiling, that counteract soiling, or from which soiling may be readily removed. Methods for minimizing soiling of radio-opaque shields are also disclosed.

Abstract: Wearable radio-opaque shields may be formed from relatively low-cost materials, which may include a non-toxic radio-opaque material. The use of such materials may render the wearable radio-opaque shields suitable for limited use or even for single use. The useful life of a wearable radio-opaque shield may be extended, and hygiene improved, by way of a liner configured for assembly with the wearable radio-opaque shield. Methods for using and disposing of wearable radio-opaque shields and liners are also disclosed.
