Patent ID: 7619226

Claim:
A radiation detection system comprising: a panel structure sized to line the interior walls of a multi-sided container; the panel structure having an annealing-resistant optical fiber therein and extending in an optical fiber path across substantially the entire area of the panel structure to envelop substantially the entire volume of the container; the annealing-resistant optical fiber having a first end and a second end; the annealing-resistant optical fiber being reactive to nuclear radiation impinging on the optical fiber to cause a change in light carrying capacity of the optical fiber; a light source optically coupled to one end of the optical fiber for introducing light; a light detector optically coupled to the other end of the optical fiber for receiving light from the optical fiber; and a circuit connected to the light detector and operative to detect the change in light carrying capacity of the optical fiber and to provide an indication thereof, wherein the optical fiber is capable of having at least one color center created therein in response to nuclear radiation impinging thereon, and wherein the at least one created color center is sensitive to a respective frequency of light from the light source.
