Casting films method for polyvinyl alcohol (PVA) doped with CrCl3 have been prepared. The electrical conductivity (σ), and dielectric constant (ε'), for unirradiated and irradiated polyvinyl alcohol (PVA) samples doped with CrCl3 with three different concentration (10, 12, and 20%wt) were studied. The samples were deposited to three different doses f -irradiation (56.1, 112.2, and 224.4KGy). The electrical conductivity, and dielectric constant in the frequency (200-105 Hz ) were measured at room temperature. The electrical conductivity increase with increasing in dopant concentration as well as -irradiation.
