multiple ion irradiation study multiple ion sequential irradiation study https://orcid.org/0000-0001-9227-0670 http://orcid.org/0000-0002-5111-7263 A multiple ion sequential irradiation study involves exposing a sample or system to a combination of different ions. This could include exposure to various forms of particle radiation such as ion beams. 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.
