Abstract
The radiation induced conductivity of post-irradiated chromium polyacrylate (CrPA) is investigated as a function of exposure rate, temperature, doping level (concentration) and field strength. The samples are irradiated with 5.5 MeV 241AM, α-source. The exposure rate is varied from 5.96×108 particles/cm2 to 3.58×109 particles/cm2. It is noted that the radiation induced conductivity in this material increases exponentially, passes through a maximum and then falls off with the increase of temperature and exposure rate. The conduction has been analyzed on the basis of the Onsager model.
