- •
We studied the degradation of PET polymeric material under reactor neutron environment.
- •
Optical and structural properties are progressively destroyed after irradiation.
- •
The band gap decreases linearly with the fast neutron fluence.
- •
The crystallinity is drastically reduced after irradiation to fast neutron fluence of 2.0×1016 n/cm2.
- •
A linear relationship between the FTIR absorption band intensity and fast neutron fluence is observed.
