ABSTRACT:
An apparatus and method for the in-situ measurement of the condition of degradable components such as electrical cable insulation, valve internals, and gaskets. A stream of energetic subatomic particles is directed to the component under test, thereby inducing the emission of secondary gamma radiation which is detected by one or more radiation detectors positioned in proximity to the component. The secondary radiation emission spectrum is recorded and analyzed to identify features and/or changes resulting from the application of one or more stressors to the component. In the specific case of aging, the radiation spectra taken from the same component at different intervals during its lifetime are compared to identify changes in the component which then may be correlated with artificially (or naturally) aged specimens to estimate the relative level of aging of the component.
