Medical isotopes form the basic ingredient of radiopharmaceutical products, which are used to detect (diagnose) or combat cardiovascular diseases and cancer cells (therapy). To detect certain diseases, a small amount of light radioactive fluid is injected into the patient.

How are isotopes being used in biology?
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.
How are isotopes used in research?
Among such prevalent uses and applications of radioisotopes are, in smoke detectors; to detect flaws in steel sections used for bridge and jet airliner construction; to check the integrities of welds on pipes (such as the Alaska pipeline), tanks, and structures such as jet engines; in equipment used to gauge thickness …
Why are radioactive isotopes useful in biological research?
Radiation in radioisotopes is useful in treating certain types of illnesses, particularly cancerous tumors. Cesuim-137 and Cobalt-60 are both used to shrink the size of tumors within the bodies of cancer patients. Cobalt-60 is also used to sterilize medical instruments.
What is an isotopic in biology?
An isotope is 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 behavior but with different atomic masses and physical properties.
What are the uses of isotopes in medicine and agriculture?
For example, radioisotopes and controlled radiation are used to improve food crops, preserve food, determine ground- water resources, sterilize medical supplies, analyse hormones, X-ray pipelines, control industrial processes and study environmental pollution.
What are 5 uses of isotopes?
What are the five applications of isotopes? Radioactive isotopes have applications in agriculture, food processing, pest control, archaeology, and medicine.
Which isotope is used in medical field?
The most common isotope used in diagnostic scans is Tc-99m (Technetium-99m), being used in approximately 85% of all nuclear medicine diagnostic scans worldwide. It is used for diagnoses involving a large range of body parts and diseases such as cancers and neurological problems.
What are radioactive isotopes and how are they used in biological sciences?
Radioisotopes can be used as tracers within a living organism to trace what is going on inside the organism at an atomic level; that is, radioisotopes can be injected or ingested by the organism, and researchers can trace the internal activities using the radioactivity.
What are some uses of radioactive isotopes in biology?
Used in genetics and molecular biology research. Used in protein studies in life science research. The most widely used radioactive pharmaceutical for diagnostic studies in nuclear medicine. Different chemical forms are used for brain, bone, liver, spleen and kidney imaging and also for blood flow studies.
How are radioactive elements used in medicine?
Nuclear medicine procedures help detect and treat diseases by using a small amount of radioactive material, called a radiopharmaceutical. Some radiopharmaceuticals are used with imaging equipment to detect diseases. Radiopharmaceuticals can also be placed inside the body near a cancerous tumor to shrink or destroy it.
What are the two uses of isotopes?
- Isotopes of Uranium (Uranium ) are used as fuels in a nuclear reactor.
- Isotopes of Is Iodine(Iodine- ) are used in the treatment of goitre.
- Isotopes of Cobalt (Cobalt ) are used in cancer treatment.
What are the different application of isotopes?
2) Isotopes are also commonly used in the laboratory to investigate the steps of a chemical reaction.
3) The isotopes of uranium is used as a fuel in nuclear reactors.
4) The isotope of iodine is used in the treatment of goitre.
5) The isotope of cobalt is used in the treatment of cancer.
What are some common isotopes used in nuclear medicine?
Iodine-131 and phosphorus-32 are examples of two radioisotopes used for therapy. Iodine-131 is used to treat the thyroid for cancers and other abnormal conditions such as hyperthyroidism (over-active thyroid). In a disease called Polycythemia vera, an excess of red blood cells is produced in the bone marrow.
What is isotope and give 5 example?
Examples of radioactive isotopes include carbon-14, tritium (hydrogen-3), chlorine-36, uranium-235, and uranium-238. Some isotopes are known to have extremely long half-lives (in the order of hundreds of millions of years). Such isotopes are commonly referred to as stable nuclides or stable isotopes.
What are 3 uses of radiation in medicine?
Radioactive iodine is used in imaging the thyroid gland. For therapy, radioactive materials are used to kill cancerous tissue, shrink a tumor or reduce pain. There are three main types of therapy in nuclear medicine. Teletherapy targets cancerous tissue with an intense beam of radiation.
What is isotope short answer?
Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. The number of protons in a nucleus determines the element’s atomic number on the Periodic Table.
What are isotopes give two examples of isotopes?
Isotopes: the atoms of the same element which have the same atomic number Z but differ in their mass number A are called isotopes. Example: Hydrogen has three isotopes ( 1 1 H , A 1 1 A 2 1 2 1 H , A 1 3 A 2 1 2 3 H ) , Protium, Deuterium, Tritium.
What are the three types of isotopes?
(The word isotope refers to a nucleus with the same Z but different A). There are three isotopes of the element hydrogen: hydrogen, deuterium, and tritium.
Why is radioactivity important in medicine?
Radiation is used in monitoring the response of tumors to treatment and in distinguishing malignant tumors from benign ones. Bone and liver scans can detect cancers that have spread to these organs. Half of all people with cancer are treated with radiation, and the number of those who have been cured continues to rise.
What type of radiation is used in medicine?
Medical radiation. X-rays, gamma rays, and other forms of ionizing radiation are used to diagnose and treat some medical conditions. This can be in the form of radiation that penetrates from outside the body, or radioactive particles that are swallowed or inserted into the body.
How is radiation used in medicine give examples and explain their significance?
The most well known is using x rays to see whether bones are broken. The broad area of x-ray use is called radiology. Within radiology, we find more specialized areas like mammography, computerized tomography (CT), and nuclear medicine (the specialty where radioactive material is usually injected into the patient).
Who discovered isotopes?
The existence of isotopes was first suggested in 1913 by the radiochemist Frederick Soddy, based on studies of radioactive decay chains that indicated about 40 different species referred to as radioelements (i.e. radioactive elements) between uranium and lead, although the periodic table only allowed for 11 elements …
What do you understand by isotopes give one example?
Isotope → Isotopes are atoms with the same number of protons, but differ in numbers of neutrons. Isotopes are different forms of a single element. Example – Carbon 12 and Carbon 14 are both isotopes of carbon, one with 6 neutrons and one with 8 neutrons.
Why do isotopes exist?
Isotopes can either form spontaneously (naturally) through radioactive decay of a nucleus (i.e., emission of energy in the form of alpha particles, beta particles, neutrons, and photons) or artificially by bombarding a stable nucleus with charged particles via accelerators or neutrons in a nuclear reactor.
