A method and apparatus for forming and reading a radiation image of an object is provided. The method is performed by placing an object of which a radiation image is to be taken adjacent a platform that is positioned between a storage layer radiation screen and an electromagnetic wave radiation source such that radiation from the electromagnetic wave radiation source which traverses the object is absorbed by the storage layer radiation screen; forming a latent radiation image of the object on the storage layer radiation screen by causing the electromagnetic wave radiation source to emit radiation, a portion of the emitted radiation traversing the object and being absorbed by the storage layer radiation screen; and reading the latent radiation image of the object from the storage layer radiation screen.

An optical fiber is surrounded by an aerogel cladding. For a low density aerogel, the index of refraction of the aerogel is close to that of air, which provides a high numerical aperture to the optical fiber. Due to the high numerical aperture, the aerogel clad optical fiber has improved light collection efficiency.
