Popis: We report chemical damage to the methine (CH) and methylene (CH2) groups in poly(allyl diglycol carbonate) (PADC), which is a polymeric nuclear track detector, under gamma rays and heavy ions (C and Kr) using Fourier Transform Infrared (FT-IR) analysis. By comparing the IR spectrum of PADC from 2700 to 3100 cm−1 to that of diethyleneglycol bis allylcarbonate (ADC), which is a monomer of PADC, we found that the peak at 2920 cm−1 was assigned to the methine group at the three-way junction. The methine group was barely damaged by gamma rays and heavy ions. It is necessary that at least two tracks interact with a single PADC unit to damage the methine group.
