Examples of isotopes and their uses

Naturally Occurring Radioisotopes Used In Industry And Science Carbon-14 Half-life - 5 715 years. This uranium isotope is used in nuclear power plants to provide nuclear power.

Used as Tracer Techniques.

Examples of isotopes and their uses. Examples of isotopes are O-16 O-17 and O-18. These isotopes can be used in forensics but are even more accurate in their ability to tell whether a certain rock originated on Earth Mars or even an asteroid. Oxygen isotopes can also tell how the oceans have been heating up or cooling down over eons.

Leading examples of isotopes. Is a carbon isotope with a half-life of 5730 years that is used in archeology to determine the age of rocks and organic matter. This uranium isotope is used in nuclear power plants to provide nuclear power.

Carbon 12 and Carbon 14 are both isotopes of carbon one with 6 neutrons and one with 8 neutrons both with 6 protons. Carbon-12 is a stable isotope while carbon-14 is a radioactive isotope radioisotope. Uranium-235 and uranium-238 occur naturally in the Earths crust.

Both have long half-lives. Radioactive isotopes may also be classified as stable isotopes when their half-lives are too long to be measured. These elements can often be found to occur in nature and include isotopes of carbon nitrogen hydrogen oxygen noble gases and metals.

For example there are a lot of carbon atoms in the universe. The normal ones are carbon-12. It also is used in plasma displays spark gaps and for leak detection.

Strontium-90 is a radioactive isotope with a half-life of 28. Sr-90 finds extensive use in medicine and industry as a radioactive source for superficial radiotherapy of some cancers. Controlled amounts of this isotope can be used in treatment of bone cancer.

Common isotopes that are used in nuclear imaging include. Fluorine-18 gallium-67 krypton-81m rubidium-82 nitrogen-13 technetium-99m indium-111 iodine-123 xenon-133 and thallium-201. The branch of medicine that uses radioactive isotopes in the diagnosis and treatment of disease.

Isotopes and Their Uses Example Paper. Isotopes Any of two or more forms of a chemical element having the same number of protons in the nucleus but having different numbers of neutrons are called isotopes. Some isotopes are unstable especially those with a lot of neutrons compared to the number of protons in the nucleus.

Major Uses of Radioisotopes. Used in many smoke detectors for homes and businesses to measure levels of toxic lead in dried paint samplesto ensure uniform thickness in rolling processes like steel and paper productionand to help determine where oil wells should be drilled. Examples of Radioactive isotopes Used In Medical Science.

Teknetum-99 Tc-99 were injected into a blood vessel will be absorbed mainly by the damaged tissue in certain organs like the heart liver and lungs. In contrast TI-201 will primarily be absorbed by healthy tissue in the hearts organs. Examples and Uses of Unstable Isotopes.

These unstable atoms have many possible applications in our lives. The isotopes of cobalt are used in nuclear medicine to stop the spread of cancer. Radioactive isotopes can be used as tracers in patients to monitor various internal processes.

In industry these elements can measure the thickness of metal. Hydrogen occurs as two isotopes. The most common hydrogen isotope has only one proton in its nucleus 1H but an isotope with 1 proton and 1 neutron also occurs.

This isotope is called Deuterium 2D. A hydrogen isotope with 1 proton and 2 neutrons is not stable but radioactive is called Tritium 3T and used in the manufacturing of nuclear. Carbon dating makes use of Carbon-14 an isotope of Carbon.

This isotope of carbon is present in the atmosphere as radioactive carbon. The amount of carbon-14 obtained in fossils help palaeontologists to calculate the age of the fossils. Uranium Isotopes are popular for its use in nuclear reactors.

U-235 is used as a fuel in nuclear reactors. Radioactive Isotopes are used for medicinal. Used as Tracer Techniques.

An object with a very small amount of a radioactive isotope attached to it or incorporated in it can readily be detected by picking up the radiation from it. A joint in a buried pipe or cable can be marked for example in this way or the efficiency of a mixing process can be followed by adding a radioactive isotope to one of the ingredients before mixing and. One excellent example of this is the use of carbon-14 to determine the steps involved in photosynthesis in plants.

We know these steps because researchers followed the progress of carbon-14 throughout the process. Authors who do not wish to use symbols sometimes write out the element name and mass numberhydrogen-1 and uranium-235 in the examples above The term nuclide is used to describe particular isotopes notably in cases where the nuclear rather than the chemical properties of an atom are to be emphasized. Naturally Occurring Radioisotopes Used In Industry And Science Carbon-14 Half-life - 5 715 years.

Used to measure the age of organic material that is up to 50 000 years old. Chlorine-36 Half-life - 301 000 years. Used to measure sources of chloride and the age of water that is up to 2 million years old.

Spectroscopy uses many unique nuclear properties of specific isotopes. For example Nuclear Magnetic Resonance NMR spectroscopy can be used only for isotopes with a nonzero nuclear spin. Isotopes commonly used for NMR spectroscopy are 1H 2D 15N 13C and 31P.

These isotopes can help determine the chemical composition and age of minerals and other geologic objects. Some examples of stable isotopes are.
