Radiation irradiation influence on the dielectric dispersion and conductivity of the widespread in the industry linear amorphous polymers: polyvinyl chloride, polymethyl methacrylate and polystyrene was ex- plored. Irradiation of baseline models was realized under temperature T = 250C by irradiation source Ra-226 during 45 days. Nucleuses Ra-226 radiate alfa-fractions of energy 4.777 MeV and gamma-quantums of energy 0,188 MeV. The study proved that changing of real parts values of complex dielectric permeability and material specific electroconductivity depends on polymer type and dose of its irradiation. The most im- portant influence of irradiation on the systems characteristics is observing for polystyrene.
