ABSTRACT:
A scintillating optical fiber sensitive to low energy radiation has a clear, solid, elongated core with a thin cladding layer surrounding substantially all of the core along substantially all the length of the core and a dye dopant dispersed within the thin cladding layer. When a low energy radiation particle contacts the thin cladding layer, energy from the particle is transferred to photons having a radiant energy frequency determined by the dye dopant color, and a fraction of the photons are transmitted through the fiber by total internal reflection. A detector using the scintillating optical fiber is also disclosed having a sensor for detecting and indicating the presence of photons operatively connected to an end of at least one optical fiber, such that when the fraction of photons are transmitted through the fiber by total internal reflection to the end, the sensor detects the photons and subsequently provides an indication that low energy radiation has been detected.
