CR-39 as a gamma dosimeter: Dielectric and infrared studies

Abstract

The relative permittivity, έ, and dielectric loss factor, tan δ, were measured in the frequency range 50–105 Hz for the solid state track detector CR-39 irradiated with γ-rays (5–100 kGy). The variation of έ and tan δ with γ-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.
