Definition
Irradiation is the process of exposing an object to ionizing radiation. This can be done for various purposes, such as sterilizing medical equipment, preserving food, or treating cancer. Think of it like giving something a controlled dose of high-energy rays. Unlike contamination, irradiation doesn't make the object radioactive. It's similar to how X-rays are used to take images, but with a higher dose of radiation for a different effect. The energy alters the object's composition or kills microorganisms.
