Radiation is an item that will automatically become glowing and will hurt objects around it. It will first simply hurt the objects. If objects get any closer, they will start glowing. Contact will kill people.
Hazmat Handlers will make this nonhazardous. In Scribblenauts, it will turn people into mutants. It can be held, but will kill whoever holds it. Putting two radiations next to each other will cause an explosion. They explode when destroyed. They come out of Nuclear Reactors.
- Despite their explosiveness, when they are nonhazardous or inexplosive, they have high health (10 plasma).
