Radicidation is a way of cleaning things using radiation. Radiation is like a special kind of superpower that can be used to kill tiny creatures that might be living on or inside things.
Imagine you have a toy that you want to make very clean. You can put it in a big machine that uses radiation to kill any little germs or bugs that might be on it. It's like a monster zapper for tiny creatures.
After the toy has been in the machine for a little while, it comes out super clean! The radiation killed any germs or bugs on it, so it's now safe to play with again.
Radicidation is used to clean lots of different things like medical equipment in hospitals, food in factories, and even sometimes the air in big buildings. So basically, radicidation is like using a special superpower to make things really, really clean!
