It is very important to measure the degree of deterioration for the cable used in long-term operated nuclear power plants. We developed the nondestructive measurement technology utilizing microwave technology to assess cable degradation. In the present study, microwave frequency of the Q-band (43GHz) was used for the dielectric absorption measurement. Presented were resonant frequency for microwave resonator measured in the temperature range from 16.9 to 24.6℃and the humidity range from 24.1 to 35.1%. In different measurement conditions, the data were discussed.
