Radioactive Half Life at Life

Radioactive Half Life. The tiny nuclear size compared to the atom and the enormity of the forces which act within it make it almost totally impervious to the outside world. Note that the nuclei turn blue when they have decayed, and the smooth purple line on the graph shows the ideal case.

Under 20 years old 20 years old level. An actual case can deviate a bit from the ideal case because of statistical fluctuations (which. 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.

Radon Gas

You can choose from three different half lives. Note that the nuclei turn blue when they have decayed, and the smooth purple line on the graph shows the ideal case. Therefore, a long half life indicates fast radioactive decay while a short half life indicates a slow radioactive day. The half life of some substances cannot be determined since it may take millions of years to undergo radioactive decay.
