Structural and Optical Investigations of Radiation Damage in Transparent PET Polymer Films

<table>FTIR spectra of unirradiated PET sample and of PET samples irradiated to various <i>γ</i>-irradiation doses: (1) 30 kGy, (2) 50 kGy, (3) 70 kGy, (4) 90 kGy, (5) 100 kGy, and (6) 135 kGy. It shows transmittance (<i>T</i>%) as a function of wavenumber (cm<sup>−1</sup>).</table>
