The ""radura"" symbol is required to be displayed on the packaging of fresh foods that have been irradiated with Ionizing radiation.
Ionizing radiation is a specific category of high-energy radiation that is powerful enough to ionize (or remove an electron, a negative particle from) an atom or molecule. Ionizing radiation has the ability to alter cellular chemistry and harm DNA.
Radiation is the broad term for energy that a source emits. The sun's heat or light, microwaves from an oven, X-rays from an X-ray tube, and gamma rays from radioactive materials are a few examples. Atoms can be ionized, or have their electrons removed, by ionizing radiation.
Ionizing radiation can injure people in two different ways, including cancer and direct tissue damage, when the dose is high enough. When enough molecules are broken apart to render the cells incapable of functioning, direct tissue damage results.
