7D10.23 - Radioactive Dating - Carbon Dating
Code Number: 7D10.23
Demo Title: Radioactive Dating - Carbon Dating
Condition: Excellent
Principle: Radioactive Decay
Area of Study: Modern Physics
Equipment:
Co-60 sources with different manufacturing dates, Counter / Scaler.
Procedure:
Cobalt-60 has a well known half life. By taking the counts from a new source and then an older source, you should be able to know exactly how much older the old source is.
