Abstract
CR-39 and SR-90 polymer samples were irradiated with γ-rays at high doses ranging from
5× 104 to 4× 105Gy. Irradiation effects were studied using Fourier Transform IR
spectroscopy (FT-IR) in transmission mode, ultraviolet-visible spectroscopy and thermo-
gravimetric analysis. Besides production of carbon dioxide due to polymerization and
irradiation processes observed by FT-IR spectrometer, the IR absorption spectra of the fresh
(non-aged) and irradiated samples also show the presence of a strong new absorption ...
