How do isotopes work?
Isotopes are atoms with the same number of protons but that have a different number of neutrons.
Since the atomic number is equal to the number of protons and the atomic mass is the sum of protons and neutrons, we can also say that isotopes are elements with the same atomic number but different mass numbers..
Why Technetium 99m is used in medicine?
Technetium-99m is a widely used radioactive tracer isotope in Nuclear Medicine. It’s gamma ray energy of about 140 keV is convenient for detection. The fact that both its physical half-life and its biological half-life are very short leads to very fast clearing from the body after an imaging process.
What are the uses of isotopes in medicine?
Radioactive isotopes have many useful applications. In medicine, for example, cobalt-60 is extensively employed as a radiation source to arrest the development of cancer. Other radioactive isotopes are used as tracers for diagnostic purposes as well as in research on metabolic processes.
What is the primary use of isotopes in medicine and biological research?
Radioactive isotopes find uses in agriculture, food industry, pest control, archeology and medicine. Radiocarbon dating, which measures the age of carbon-bearing items, uses a radioactive isotope known as carbon-14. In medicine, gamma rays emitted by radioactive elements are used to detect tumors inside the human body.
Are isotopes good or bad?
They are radioactive, and can be harmful and kill organisms. … And of course, a RADIOISOTOPE, is basically a radioactive isotope. Isotopes have the same chemical properties with that of the “original” element. But, their physical properties differ.
Why are some isotopes Radioactive?
Many elements have one or more isotopes that are radioactive. These isotopes are called radioisotopes. Their nuclei are unstable, so they break down, or decay, and emit radiation. … A: The nucleus may be unstable because it has too many protons or an unstable ratio of protons to neutrons.
What are the advantages of radioisotopes?
radioactive isotopes give doctors the ability to “look” inside the body and observe soft tissues and organs. Radioisotopes carried in the blood also allow doctors to detect clogged arteries or check the functioning of the circulatory system.
What are 4 uses of radioactive isotopes?

What are two examples of isotopes?
Isotope Examples Uranium-235 and uranium-238 are two isotopes of uranium. Both are natural isotopes that are found in the Earth’s crust. Carbon-12 and carbon-14 are two carbon isotopes. Carbon-12 is stable, while carbon-14 is radioactive.
What do isotopes tell us?
It is the electrons that determine the chemical behaviour of a particular element. Isotopes of an element share the same number of protons but have different numbers of neutrons. … This means that all three isotopes have different atomic masses (carbon-14 being the heaviest), but share the same atomic number (Z=6).
What are 3 examples of isotopes?
Isotopes ExamplesCarbon-14. A naturally occurring radioactive isotope of carbon having six protons and eight neutrons in the nucleus. … Iodine-131. It is an isotope because it contains a different number of neutrons from the element iodine. … Tritium.
How are radioactive isotopes used to diagnose medical conditions?
Radioisotopes are widely used to diagnose disease and as effective treatment tools. For diagnosis, the isotope is administered and then located in the body using a scanner of some sort. The decay product (often gamma emission) can be located and the intensity measured.
Why is an isotope important?
Isotopes of an element all have the same chemical behavior, but the unstable isotopes undergo spontaneous decay during which they emit radiation and achieve a stable state. This property of radioisotopes is useful in food preservation, archaeological dating of artifacts and medical diagnosis and treatment.
What isotope means?
Isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties. Every chemical element has one or more isotopes. Isotope. key people.
How are isotopes detected?
Summary. Atoms that have the same number of protons but different numbers of neutrons are known as isotopes. Isotopes have different atomic masses. … The relative abundance of each isotope can be determined using mass spectrometry.
What are 3 uses of radioisotopes?
Different chemical forms are used for brain, bone, liver, spleen and kidney imaging and also for blood flow studies. Used to locate leaks in industrial pipe lines…and in oil well studies. Used in nuclear medicine for nuclear cardiology and tumor detection. Used to study bone formation and metabolism.
What radioactive isotopes are used for medical treatment?
The radioisotope most widely used in medicine is Tc-99, employed in some 80% of all nuclear medicine procedures. It is an isotope of the artificially-produced element technetium and it has almost ideal characteristics for a nuclear medicine scan, such as with SPECT.
What are the uses of radioactive isotopes in industry?
Radioisotopes are used by manufacturers as tracers to monitor fluid flow and filtration, detect leaks, and gauge engine wear and corrosion of process equipment. Small concentrations of short-lived isotopes can be detected whilst no residues remain in the environment.
Why are radioisotopes bad?
Radioisotopes – bad or good? The more familiar types of this radiation are alpha particles, beta particles and high-energy gamma rays. High-energy gamma radiation is very penetrating and, if the dose is high enough, can damage living cells beyond repair.
What is the difference between a nuclide and an isotope?
Nuclides vs isotopes The nuclide concept (referring to individual nuclear species) emphasizes nuclear properties over chemical properties, while the isotope concept (grouping all atoms of each element) emphasizes chemical over nuclear.
