ABSTRACT:
A dosimeter with reproducible changes in .epsilon.', .epsilon.'', or their equivalent two parameter circuit representations, under a given treatment regime that correlate directly with changes in physical attributes of a material or fluid, such as strength, modulus or viscosity, is used to monitor the deterioration of the physical attributes of the material or fluid.
