Carbon dating fossil

Since it is radioactive, it gradually fades away by radioactive decay until it is all gone.Radiocarbon dating uses carbon-14 to determine the last time something (or someone) was alive.Their bodies are said to be in “equilibrium” with carbon-14 in the air.Although carbon-14 is radioactively decaying away in the body, it is constantly being replaced by new photosynthesis or the ingestion of food, leaving the amount relatively constant.

This leaves the amount in the air relatively constant.Radiocarbon dating is applicable to biobased content measurements in manufactured products because they contain some combination of recently living materials and fossil materials.The standard developed for this purpose is called ASTM D6866.It then uses this information to determine the last time the fossil was respiring carbon (i.e. A radiocarbon dating lab is able to do this using the known “half-life” of carbon-14.The half-life of carbon-14 is the amount of time it takes for one-half of the original amount to disappear by radioactive decay.
