[Free Registration/Login may be required to access all resource tools.] An overview of radioactive decay.

[Free Registration/Login may be required to access all resource tools.] An overview of radioactive decay.

[Free Registration/Login may be required to access all resource tools.] The half-life of a radioisotope, rates of radioactive decay and variation in half-lives in different radioisotopes.

Toss 100 pennies (or poker chips or any other two-different-sided objects) and remove all of those displaying tails. Line them up and repeat. The lines of pennies collected get smaller each time, successfully representing half-life.

This digital textbook covers core physical science concepts and includes interactive features, real world examples, and videos.
