Editing Radioactivity (section)

== Demonstration ==


# Show the pieces of Fiestaware to the students. Allow them to hold the pieces and look at them, and explain that the pieces are glow-in-the-dark due to the paint on them. Then, explain that unlike all the modern glow-in-the-dark things we have, this paint glows because it was made with radioactive materials.
# Using the Dosimeter, show the students that the pieces of plate give off a strong reading. Explain to them the three types of radiation, and the two that the plate gives off.
# Show them the Uranium sample and the trinitite sample. If they wish, let them hold the samples and explain what types of radiation they give off.
# Show the Geiger Counter, and explain how it would detect particles using the "wand", and how that same technology is in the Dosimeter. You can also point out the small radioactive sample that is on the front of the Geiger Counter, which would be used to calibrate the detector.
# Explain to the students that they interact with several radioactive materials all the time in their everyday activities. List off things such as:
## Concrete (Alpha-decay)
## Sunlight (Gamma-decay)
## Banana's (fun fact: "one banana" is actually a measure used in Nuclear Physics, and is equal to one microSeivert.
## The air (Main source of background radiation)
# Let students know that we are radioactive as well! Have them hold out an arm, and if you hold the Dosimeter against it you can get faint readings.
