Use of radio isotopes in carbon dating

Use of the isotopes can advance the agriculture output and also minimize the amount of nitrous oxide and methane discharge... Radioactive isotopes in medicine are used to help diagnose certain disease states and isolate regions in the body. An element's isotopes differ in the number of neutrons.

Chemically, all the isotopes of an element are the same.

They differ in atomic weight because of the difference in neutrons.

In common use, the word isotope usually refers to the less stable isotopes of an element, which break down through radioactive decay.

D2O water is therefore much heavier than normal H2O water.

As water is widely used in most metabolic pathways, "marking" with D2O can let you find the isotope in different parts of the organism and it's products.

- Isotopes can be used as tracers - Isotopes can be used as energy source - Isotopes are used for radioactive dating - Isotopes are used in chemical analysis - Isotopes are used in many instruments - Isotopes are used as source of nuclear energy in bombs and nuclear reactors etc.

It was discovered in 1934 by Grosse as an unknown activity in the mineral endialyte. This half life has later been re-determined by Godwin. Libby recognized that due to its occurrence in natural materials, either by simple mixing processes or by carbon exchange.

The use of nuclear energy in civilian society is to generate electricity.These features can be used to reconstruate cellular growth processes, as well as in other organisms bodily functions and development.Hydrogen has three isotopes, one of them deuterium (features one neutron), which makes it twice as heavy as normal hydrogen.They are then able to calibrate the carbon dating method to produce fairly accurate results.Carbon dating is thus accurate within the timeframe set by other archaeological dating techniques.
