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.
