Abstract Induced variations of electrical conductivity σdc of polyaniline by γ-radiation have been studied, σdcdc increases from 2.2 to 2.7S/cm due to radiation with a dose of 30-40Mrad. EPR results show that spin concentration increases at the same rate as σdc. The characteristics of σdc versus temperature fit to Inσdc∝T-1 before irradiation, before irradiation, but to Inσdc∝T-1/4 after irradiation.
