Measurement of 60CO gamma radiation induced attenuation in multimode step-index POF at 530 nm
2013
As optical fibres are used ever more extensively in space applications,
nuclear industry, medicine and high-energy physics experiments, it has become
essential to investigate the influence of ionizing radiation on their
characteristics. In this work, the radiation-induced attenuation at 530 nm is
investigated experimentally in step-index multimode polymethyl-methacrylate
plastic optical fibres exposed to low dose-rate gamma radiation. Cumulative
doses ranged from 50 Gy to 500 Gy. The radiation induced attenuation has been
empirically found to obey the power law RIA= aDb, where D is the total
radiation dose and a and b are the constants determined by fitting.
