|Title:||Measurement of <sup>60</sup>CO gamma radiation induced attenuation in multimode step-index POF at 530 nm|
|Authors:||Kovačević, Milan |
|Abstract:||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.|
