Josie acts like Madam Curie to explain how she discovered radiation and how it works. Beakman talks about how the fission of atoms produces heat, which makes radioactive materials glow. Beakman sets up a demonstration with mousetraps and ping pong balls (atoms) where he hits one and it causes a chain reaction of all of the mouse traps triggering.

The Planeteers visit Chile and see that animals have gone blind and have rashes due to the sun.

This clip highlights some of Marie Curie's greatest contributions to science: the theory of radioactivity and the discovery of radium.

The Planeteers warn kids and parents of the dangers of radiation and harsh chemical solvents as well as ways to reduce pollution by the careful disposal of toxic waste.

Duke Nukem unveils his latest scheme to get radiation to feed on - using CMCs to burn holes in the Ozone Layer and magnify solar radiation through a giant lens to himself.
