Radiation testing is a specialized methodological approach used to evaluate the effects of radiation on materials, components, or systems, or to characterize radiation fields themselves. It involves controlled exposure to various radiation types, such as ionizing particles or electromagnetic radiation, or the measurement of ambient radiation levels using specific instrumentation. This research investigates performance degradation, damage mechanisms, dose responses, and safety implications. The field is critical for developing radiation-hardened technologies, ensuring safety in radiation environments, and validating models of radiation interaction across diverse applications in fields like aerospace, nuclear engineering, and medical physics.
