Abstract
Irradiation of optical fiber waveguides by ionizing radiation can cause an increased loss in optical transmission. The effect of the loss has been measured on several commercially available pure silica core boron-doped clad fibers irradiated with thermal neutrons from a nuclear reactor. In the present work, optical absorptions were measured over the 400-1100nm range during the neutron irradiation. We have found that the attenuation of optical transmission by thermal neutrons is caused by defects produced by alpha particles which are produced in boron-neutron reactions.
