The stability as well as the electrical properties of both unirradiated and γ-irradiated poly(vinyl alcohol)-PVA films doped with MnSO 4 .H 2 O at a definite concentration of 15% have been studied.The dielectric loss tangent tan δ, electrical conductivity σ and dielectric constant ε' in the frequency range 100 Hz-20 KHz were measured at different temperatures.It has been demonstrated that the suit...
