👉 In the context of radiation physics, "unirradiated" refers to a type of material that has been irradiated with high-energy electrons or protons. This means that the material has absorbed enough energy from the electrons or protons in order to be ionized and released as particles such as ions, electrons, or alpha particles. The term is often used to describe materials that have undergone intense exposure to radiation. For example, a type of unirradiated glass would be one that has
