Radiothermoluminescence Study on Several Polymers.


Abstract:
A survay on the radiothermoluminescenceof 25 polymers is presented. The RTL glow curves were recorded on the temperature range starting from 77 K up to room temperature after 60Co irradiation. The most RTL peaks occur at temperatures similar to those assigned to the onset of specific molecular motins, suggesting that the peaks are due to the liberation of electrons from traps formed by the chains of polymer. The RTL glow curves are generally in good agreement with the results reported by other researchers. This paper includes the experimental data obtained from each glow curve (temperature and intensity of maxima). The activation energies of some of the peaks were obtained using several methods. The peaks with lower activation energies generally are located at lower temperatures. Keywords: polymers, elastomers, radiothermoluminescence, characterization, activation energy
