Gcse Physics Radioactive Decay And Half Life 35 Youtube This video covers: how radioactive decay works what activity means the two definitions of half life how to show radioactive decay on a graph how we can. The half life of radioactive carbon 14 is 5,730 years. if a sample of a tree (for example) contains 64 grams (g) of radioactive carbon after 5,730 years it will contain 32 g, after another 5,730.
