Food Irradiation
Food irradiation is a way to kill germs in meat and other foods using energy beams.
Think of it this way
Sunlight shines through a glass of water and kills germs inside it. The light passes through without heating the water or changing how it looks. Food irradiation works the same way. Energy beams pass through meat or fruit, break apart the germs, and leave the food cool and unchanged.
Explaining food irradiation by grade level
Think about a piece of raw beef from the store. It can have tiny germs on it that make people sick. A special beam of energy passes through the meat. The beam kills the germs but does not cook the meat or change how it looks.
