In our study, 10 specimens of commercially available coaxial cable were exposed to gamma irradiation using two different dose rates and five different total doses. Then, the sound velocities were measured using traditional pulse-echo approach with an integrated transducermicrometer setup developed by VTT. EaB values were measured via tensile testing by ÚJV. The results clearly show, that sound velocity increases and EaB decreases when polyethylene is exposed to gamma irradiation. The correlation between sound velocity and EaB is linear. Based on the results, it is possible to use sound velocity as a low-cost nondestructive indicator for gamma-irradiation induced degradation of polyethylene.
