Abstract
Optical fibers of silica and plastic composition are rendered relatively stable to nuclear radiation induced optical losses by preirradiating with a high initial radiation dosage. Subsequent exposure of the radiation hardended fibers produce substantially lower radiation induced optical loss and faster fiber transmission recovery rates.
