Abstract: A feedthrough device includes a body having longitudinally spaced first and second end faces and an inner surface defining an opening extending longitudinally through the body, a conductor extending within the opening of the body, and an insulator extending within the opening of the body transversely intermediate the conductor and the inner surface of the body to insulate the conductor from the body, where the conductor includes an interior portion surrounded by the insulator and an exterior portion extending beyond the insulator, the exterior portion having a diameter that is greater than a diameter of the interior portion.

Abstract: The presently claimed and disclosed inventions relate, in general, to methods of radiation dosimetry and imaging using scintillation luminescence. More particularly, materials having a scintillation luminescence response to radiation that varies with total radiation dose received can be used for dosimetry monitoring, including, but not limited to nanoparticles for in vivo, real-time dosimetry. Energy-transfer nanocomposite materials as well as methods of making and using such materials in various applications including, but not limited to, in vivo radiation dosimetry and imaging, are disclosed. More particularly, the presently claimed and disclosed inventions relate to nanoparticle scintillation luminescence particles encapsulated in hosts of the general formula BaFX and BaFX:Eu2+ where X?Cl, Br and I.
