14 Example con’t

15  Radioactive elements disintegrate spontaneously.  Experiments show that the rate of disintegration is proportional to the amount of material present as we have seen with medicine, population, disease, etc.  These facts can be used in carbon dating to estimate the age of an artifact that contains plant or animal material. Radioactive Decay

16 Radioactive Decay Example
