Abstract: A radiation exposure indicator device is described comprising glass which provides a directly visually observable color change upon exposure to radiation, wherein the glass is in the form of glass fibers. A method of detecting exposure of an item to irradiation is also described, comprising attaching a radiation exposure indicator to the item or packaging thereof, the exposure indicator comprising glass which provides a visually observable color change upon exposure to radiation wherein the glass is in the form of glass fibers, and monitoring the exposure indicator for a visual color change. The present invention provides a passive dosimeter which may be affixed to or integrated into various items (e.g., mail, envelopes, stamps, labels, over-packs, packages, shipping containers, etc.) which is inexpensive to manufacture, while providing design flexibility to enable fabrication into a variety of desired shapes and sizes.
