The phrase "irradiated materials" refers to objects or substances that have been exposed to radiation. Radiation is a type of energy that can cause changes in these materials, either by altering their properties or damaging them. Full definition
«The atomic structure of irradiated materials is actually closer to that of a liquid than to that of a glass,» Bauchy said. (sciencedaily.com)
Today, most irradiated materials testing involves designing a material, exposing it to radiation, and destructively testing the material to determine how its performance characteristics change. (sciencedaily.com)
«This is quite surprising because glasses and heavily irradiated materials typically exhibit the same density, so that glasses are often used as models to simulate the effect of the exposure to radiations on materials.» (sciencedaily.com)
