Radioisotopes are an essential part of medical diagnostic procedures. In combination with imaging devices which register the gamma rays emitted from within, they can be used for imaging to study the dynamic processes taking place in various parts of the body.

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.
Why are isotopes important in the body?
The isotopes, used in conjunction with sophisticated equipment, give medical professionals a powerful “window” into the body, allowing them to diagnose diseases, study biological processes and investigate the movement and metabolism of drugs in living people.
Why do we use radioisotopes in medicine?
Radioisotopes in medicine. Nuclear medicine uses small amounts of radiation to provide information about a person’s body and the functioning of specific organs, ongoing biological processes, or the disease state of a specific illness. In most cases the information is used by physicians to make an accurate diagnosis.
What is the primary use of isotopes in medicine and biological research?
Isotopes are used as tracking devices, image enhancers, and age determinations.
What are three uses of isotopes?
Give three application of isotopes.
- Smoke Detectors.
- Archaeological Dating.
- Medical Use (Nuclear Medicine)
- Food Irradiation ( to take away all the harmful substances in food and to make it more safetier for eating)
- Agricultural Application – radioactive tracers.
What isotopes are used for diagnosing and treating illness and diseases?
The most common radioisotopes used in the medical industry are Technetium-99m, Iodine-131, and Molybdenum-99. 85% of all nuclear medical examinations use Mo/Tc generators for diagnosing problems with the liver, bones, or lungs .
How are isotopes used in the human body?
Stable isotopes have been used as tracers in human nutritional studies for many years. A number of isotopes have been used frequently to assess body composition, energy expenditure, protein turnover and metabolic studies in general, such as deuterium (2Hydrogen), 18Oxygen, 13Carbon and 15Nitrogen.
What is the function of isotopes?
They are typically useful when performing experiments in the environment and in the field of geochemistry. These isotopes can help determine the chemical composition and age of minerals and other geologic objects. Some examples of stable isotopes are isotopes of carbon, potassium, calcium and vanadium.
How radioactive isotopes are used for medical diagnosis and treatment?
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.
What are three uses of radioactive isotopes in medicine?
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.
Where do medical isotopes come from?
Medical isotopes come either from nuclear reactors or cyclotrons. The most significant quantities of radioisotopes rich in neutrons (i.e. Mo-99) come from neutron bombardment in a nuclear reactor. Cyclotrons are used to produce isotopes rich in protons.
Why are some isotopes radioactive?
Radioactive isotopes decay spontaneously because their nuclei are unstable. According to the theory, If the ratio of neutrons to protons more than one, or becomes too large, the isotope is radioactive or the atomic number is above 83, the isotope will be radioactive.
How are isotopes used in medicine and biological research?
Nuclear medicine uses radioactive isotopes in a variety of ways. One of the more common uses is as a tracer in which a radioisotope, such as technetium-99m, is taken orally or is injected or is inhaled into the body. Therapeutic applications of radioisotopes typically are intended to destroy the targeted cells.
What is the primary use of isotopes in medicine and biological research quizlet?
What is the primary use of isotopes in medicine and biological research? To obtain 3-d images and physiological information about body function without using surgery.
Why is it possible to use isotopes to study biological molecules?
Radioactive isotopes and radioactively labelled molecules are used as tracers to identify abnormal bodily processes. This is possible because some elements tend to concentrate (in compound form) in certain parts of the body – iodine in the thyroid, phosphorus in the bones and potassium in the muscles.
