mixed ion and photon irradiation study mixed ion and photon simultaneous irradiation study A mixed ion and photon simultaneous irradiation study typically involves simultaneously exposing a sample or system to a combination of these types of radiation. This could include exposure to various forms of ionizing radiation, such as gamma rays, X-rays, and particle radiation. Exposure might be from anthropogenic or natural sources of radiation. The goal is to understand how the different types of radiation interact with each other and their combined effects on the material or biological system under investigation. https://orcid.org/0000-0001-9227-0670 http://orcid.org/0000-0002-5111-7263
