Radiation Safety Simulation
Stay safe like a real scientist — practice using distance and shields!
Marie Curie did not know how dangerous radiation was at first. Today, scientists stay safe by using barriers and measuring exposure. Try this safe simulation to see how it works!
What You Will Need:
Flashlight (as the “radiation source”)
Cardboard or plastic sheet (as a shield)
Small toys or paper figures
Tape measure or ruler
Stopwatch or timer
Step-by-Step Instructions:
Tape your flashlight to the table, pointing in one direction.
Place your toy figures at different distances from the light.
Add cardboard between the light and the figures — does it block the light?
Use a timer to see how long each figure stays “exposed.”
Move figures and shields around to see what changes.
What to Look For:
What happened when you added more distance?
Did the cardboard shield make a difference?
What method kept your figure safest?
Curie Fun Fact!
Even though she did not know it, Marie Curie carried radioactive materials in her pockets while working!
Safety Tip:
Never play with real radiation. This activity is just a light-based model — but scientists always use protective gear.
