Neutrons from a research reactor can interact with atoms in a sample causing the emission of gamma rays which, when analysed for characteristic energies and intensity, will identify the types and quantities of elements present.Some radioisotopes used in nuclear medicine have very short half-lives, which means they decay quickly others with longer half-lives take more time to decay, which makes them suitable for therapeutic purposes.

Most commercial analysers use californium-757 neutron sources together with sodium iodide detectors and are mainly sensitive to TNC reactions.

By measuring radioisotopees amount of carbon left in dead organic material the approximate time since it died can be worked out.

For example, intwo hikers discovered a mummified man, preserved for centuries in the ice on an alpine mountain. Uranium has a very long half-life and so by measuring how much uranium is left in a rock its approximate age can be worked out. You're using the Internet Explorer 6 browser to view the BBC website.
