Thank you for using the Jiskha Homework Help Forum. Although you don't reference this specifically, do you mean the game?

Since this is not my area of expertise, I searched Google under the key words "'half life'" to get these possible sources:
http://en.wikipedia.org/wiki/Halflife
http://www.colorado.edu/physics/2000/isotopes/radioactive_decay3.html
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps. Thanks for asking.
