Solarization-resistant fibers are a class of specialty fibers resistant to UV radiation. They may also be described as radiation-hardened or radiation-tolerant. Though there are many methods of enhancing radiation resistance, two proven methods include using hydrogen saturation or treating the environment with Deuterium. Incorporating hydrogen loading, alongside a coating of carbon, to prevent the hydrogen from breaking away, can also be used with silica core fibers to increase their radiation hardness, as shown within the study by Andreenko et al.¹  Moreover, deciding upon a category of fiber, one of which can withstand radiation, can be achieved through an in-situ gamma radiation test, which was demonstrated through the examination of the fiber optics selection used in H-alpha diagnostics.²
