"""A diagram is shown. A gray box on the left side of the diagram labeled """"Lead block"""" has a chamber hollowed out in the center in which a sample labeled """"Radioactive substance"""" is placed. A blue beam is coming from the sample, out of the block, and passing through two horizontally placed plates that are labeled """"Electrically charged plates."""" The top plate is labeled with a positive sign while the bottom plate is labeled with a negative sign. The beam is shown to break into three beams as it passes in between the plates; in order from top to bottom, they are red, labeled """"beta rays,"""" purple labeled """"gamma rays"""" and green labeled """"alpha rays."""" The beams are shown to hit a vertical plate labeled """"Photographic plate"""" on the far right side of the diagram."""
