초록

The value of charge current, discharge current, $\varepsilon_r$' $\varepsilon_r"$, residual voltage was measured inorder to investigate electric properties in Ethylene Prophylene Rubber for is irradiated $CO^{60}\gamma$ ray 0-38.1 Mrad. The value of charge current and the discharging current of the EPR is influenced by $CO^{60}-{\gamma}$-irradiation dose The charging current and the discharging current of EPR increase, depending on the ratio of degradation. As the irradiation dose is increased, the peak of residual voltage moves to the slorter time. The properties specific electric constant due to time variation was appeared dispersion by plentiful $CO^{60}-{\gamma}$-irradiation dose. The increase of peak in $\varepsilon_r"$ is attrib uted to the irratiation dose almost proportionally.
