| Abstract: | The relative permittivity,  , and dielectric loss factor, tan  , were measured in the frequency range 50–105 Hz for the solid state track detector CR-39 irradiated with  -rays (5–100 kGy). The variation of and tan with -dose have been interpreted in terms of structural changes as emphasized from infrared spectra. A mathematical model has been introduced describing the use of CR-39 as a dielectric dosimeter. |
