Paper Abstract

The radiation induced loss of multimode lead glass fibers is measured during and after irradiation by a Co-60 source in the temperature range from 10 degree(s)C to 50 degree(s)C. The measurements were performed at visible and infrared LED wavelengths using time multiplexing of the LED's. The radiation sensitivity and relaxation effects of this fiber depend on temperature and on the wavelength of the read-out light. The wavelength dependence allows estimation of the actual fiber temperature. Thus a method can be developed to compensate temperature and fading effects on radiation induced loss in situations where the fiber temperature is unknown. The application of multiple wavelength measurements of induced loss for radiation dosimetry with optical fibers is discussed.
