# How are half lives used in radioactive dating

Radioactive decay: ever heard of plutonium it's the stuff we use in our nuclear things -- weapons, submarines, etc plutonium-239 has a half-life of 24,110 years half-life means that, if you have 100 pounds of plutonium-239. Information on radioactive half-life and carbon dating for more details on these subjects radiometric dating activity background information :. Radioactive dating because the radioactive half-life of a given radioisotope is not affected by temperature, physical or chemical state, or any other influence of the environment outside the nucleus save direct particle interactions with the nucleus, then radioactive samples continue to decay at a predictable rate and can be used as a clock. Permalink the reliability of percentage remaining (50% of the remaining rule) that has been used by scientists for the relative half-lives elapsed in responding to radiometric dating method is in question. This final expression is known as the radioactive decay law it tells us that the number of radioactive nuclei will decrease examples of the half lives of some.
