WebThe radiation-induced attenuation of PMMA plastic optical fibre is monitored in realtime during irradiation. The fibre exhibited a linear radiation-induced attenuation response at various wavelengths for a dose range of 50Gy to 50kGy. WebTo address this issue, surface modification of the PMMA optic stem is being studied, with encouraging results showing improved biocompatibility and biointegration between the …
