Effect of Gamma Radiation on Charge Storage in PTFE Exposed to Electron Beam

In this work, we focus our attention on data obtained from Pulse Electro Acoustic (PEA) measurements on PTFE films before and after irradiation with a
⁶⁰
Co gamma radiation source. At first, samples are just polarized to determine the effect of the gamma irradiation on the charge transport in the bulk. In a second stage, these films have been exposed to a mono-energetic electron beam. The aim is to study the effect of gamma radiation on charge storage in the bulk.
