Radioisotope

The radioisotopes , radionuclides or radioelements , contraction of Radioactivity and Isotope , are Atome S whose core is unstable. This instability can be due either to an excess of Proton S or Neutron S, or with an excess of both. The radioisotopes exist naturally or are produced artificially by bombarding minor amounts of matter with neutrons, usually produced in a Nuclear reactor.

In Medicine, the radioisotopes are largely used at ends of diagnosis or research. The radioisotopes present naturally or introduced into the body, emit gamma rays and, after detection and treatment of the results, provide information on the Anatomie of the person and on the operation of some specific Organe S. When they are used thus the radioisotopes are called tracer. The Radiothérapie uses also radioisotopes in the treatment of some Maladie S like the Cancer. Powerful sources of gamma rays are also used for to sterilize the medical device. In the Western countries, approximately a person on two is likely to profit from the Nuclear medicine during her life, and the sterilization by irradiation gamma is almost universally used.

In industry, the radioisotopes are used to examine the weldings, to detect the escapes, to study tiredness of the metals and for any kind of analyzes on materials like minerals.

Many smoke detectors use a radioisotope derived from the Plutonium or Américium produces artificially. These detectors already saved many lives.

The radioisotopes are used to follow and analyze the pollutants, to study the movement of surface water, to measure the flow of the Pluie and the Neige, as well as the flow of the rivers.

A great quantity of radionuclides are propelled in the terrestrial atmosphere and fall down more or less quickly on the ground at the time of a nuclear catastrope (such as the Catastrophe of Tchernobyl) or during the explosion of a atomic bomb or at the time of a Nuclear test.
