Abstract
The loss induced in PM fibers by low dose rate (less than 1 rad/h) irradiations is evaluated, and the radiation response varies from less than 0.4 to about 6 Db/km-krad, depending on the wavelength of measurement and the fiber. The 'permanent' induced loss determined by fitting the recovery of the induced loss following high-dose-rate exposure to nth-order kinetics is shown to be a valid predictor of the low-dose-rate response; both 0.85- and 1.3-micron PM fibers have been found which show virtually no permanent incremental loss and would therefore appear to be resistant to low-dose-rate radiation environments. In addition, explicit measurements are given for the differential incremental attenuations of light traveling in the two orthogonal polarization axes induced by both steady state Co-60 and pulsed electron irradiations. Significant differential attenuation is only evident at high doses and short times.
