This article explores the consequences of neutron irradiation on the characteristics of polyethylene used as sample shuttles sent for prolonged irradiation (3 hours) in the core of the TRIGA Mark II reactor.The results reveal alterations in the mechanical, thermal and chemical properties of polyethylene following neutron irradiation.Conclusions drawn from two distinct approaches -infrared and X-ray imaging -underscore the importance of understanding the impacts of neutron irradiation on materials intended to be exposed to neutron fluxes.This understanding is crucial to ensuring the safety and durability of these materials.
