Learning Goal: The goal of this project was to learn about radioactive decay, and how it interacts with different mediums.
Now before I continue, a brief note on safety.
THIS PROJECT USES A SMALL AMOUNT OF RADIOACTIVE MATERIAL.
A small radio active source extracted from a smoke detector is used. It should not be too much of a concern, but it is not to be taken lightly. The sample is made is made from Americium-241, which is a strong alpha emmiter. At atmospheric pressures alpha particles can only travel a few centimeters, but do take caution.
DO NOT SWALLOW THE SAMPLE
DO NOT CARRY THE SAMPLE IN YOUR POCKET
AVOID HANDLING THE SAMPLE LONG PERIODS OF TIME
LIMIT YOUR EXPOSURE BY NOT KEEPING THE SAMPLE NEAR YOU AND STORING IT IN A STEEL OR ALUMINUM CASE
MAKE SURE THE CASE IS CLEARLY MARKED TO PREVENT OTHERS FROM HANDLING IT
Okay that being said I take no responsibility something bad happens doing this project. So long as you use common sense it should be fine.
Judges see last step for contest info.
Look closely at the video and you should see the small white flashes, the tell-tale sign of alpha particles interacting with the CMOS.
