British Broadcasting Corporation Home. There are three main types of radiation, called radiocarbon dating bitesize, beta and gamma radiation, radiocarbon dating bitesize all have different properties. The half-life of a radioactive isotope is the time taken for half its radioactive atoms to decay. Nuclear equations describe what happens during alpha and beta decay. The nuclei of radioactive atoms are unstable.

They break down and change into a completely different type of atom. This is called radioactive decay. The radioactivity of an object is measured by the number of nuclear decays it emits each second — the more it emits, the more radioactive it is. It is not possible to predict when an individual atom might radiocarbon dating bitesize. But it is possible to measure how long it takes for half the radiocarbon dating bitesize of a piece of radioactive material to decay.

This is called the half-life of the radioactive isotope. There are two definitions of half-life, but they mean essentially the same thing. Half-life is the time taken for:. Different radioactive isotopes have different half-lives. For example, the half-life of carbon is 5, years, but the half-life of francium is just 20 minutes. Radioactivity decreases with time.

It is possible to find out the half-life of a radioactive substance from a graph of the count rate against time. The graph shows the decay curve for a radioactive substance. In the graph above, the count rate drops from 80 to 40 counts a minute in two days, so the half-life is two days. In the next two days, it drops from 40 to 20 - it halves. In the two days after radiocarbon dating bitesize, it drops from 20 to 10 - it halves again - and so on.
