Abstract
An interferometric method is discussed which enables changes in refractive index of irradiated optical fibers to be determined. The method was used to determine the changes of step-index fibers irradiated with 1 krad of γ rays from a 60Co source. In one case, relative changes in the core and cladding radii of 3.9‰ and 1.8%, respectively, and in the core and cladding refractive indices of 2.8‰ and 2.26‰, respectively, have been determined.
