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.

What are some practical uses for radioactive substances?
Radioactivity has several practical applications, including tracers, medical applications, dating once-living objects, and the preservation of food.
How radioactive isotopes are used in biological research and medicine?
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.
How does radioactivity relate to biology?
Radioactivity is generally used in life sciences for highly sensitive and direct measurements of biological phenomena, and for visualizing the location of biomolecules radiolabelled with a radioisotope.
Which radioactive element are used in biological research?
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. Some radioisotopes are used to diagnose and treat other disorders, such as Chromium-51, which helps doctors determine the survival rate of red blood cells.
What are common isotopes discussed in biology?
Isotopes are different forms of the same element that have the same number of protons, but a different number of neutrons. Some elements, such as carbon, potassium, and uranium, have naturally occurring isotopes. Carbon-12, the most common isotope of carbon, contains six protons and six neutrons.
What are the three application of radioactivity?
Uses of radioactivity Medical use: Many diseases such as cancer are cured by radio therapy. Sterilization of medical instruments and food is another common application of radiation. 2. Scientific use: Alpha particles emitted from the radio isotopes are used for nuclear reactions.
How are radioisotopes used in scientific research?
Radioisotopes can be used to study and detect water resources and detect the presence of pollution. They can also be used in soil and water exposure studies. In these fields, harmless radioactive tracers are used to see how water moves through an area and how easy it is for pollution to move from one area to another.
Why are radioactive elements useful for the study of biological systems?
Why are radioactive elements useful for the study of biological systems? They can be traced as they travel through the body. For example, they can concentrate around a tumor, and with our technology, we can detect where the concentration is.
What is radioactive in biology?
As its name implies, radioactivity is the act of emitting radiation spontaneously. This is done by an atomic nucleus that, for some reason, is unstable; it “wants” to give up some energy in order to shift to a more stable configuration.
How is radioactivity used in science?
Scientists and engineers use radioactivity as a source of heat for satellites, for medical imaging, for targeted cancer treatments, for radiometric dating, and for research into the laws of nature and the origin of matter.
How are radioisotopes used in agriculture?
More than 60 countries worldwide have introduced regulations allowing the use of irradiation for food products including spices, grains, fruit, vegetables, and meat. It can replace potentially harmful chemical fumigants that are used to eliminate insects from dried fruit and grain, legumes, and spices.
What are radioisotopes and examples?
(a).The isotopes which are unstable due to presence of extra neutrons in their nuclei and emit various types of radiations, are called radioactive isotopes or radioisotopes. For example: Carbon – 14 , Arsenic – 74. (b). Uses of isotopes-
What does isotope mean 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.
How are isotopes used in biochemistry?
One of the most important applications of radioisotopes in biochemistry is their use in determining metabolic pathways and for measuring the flow of metabolites through pathways. Radioisotopic methods have been developed to trace and assay enzymic reactions.
Why are radioactive isotopes referred to as biological spies?
Radioactive isotopes are called “biological spies” because they give scientists an insight into the activity of atoms in living organisms. Radioactive isotopes are easily detectable using technology, so their radioactive residue can be easily traced within organisms and analyzed.
What are the 2 application of isotopes?
Solution : Applications of isotopes :
1) Some isotopes are used for solving chemical and medical mysteries.
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.
What are the two major applications of radioisotopes in nuclear medicine?
There are two uses of radioisotopes: they can be utilised as a source of radiation energy and as a diagnostic tracer.
Which isotope is used in treating leukemia?
A radioactive form of the element phosphorus. It is used in the laboratory to label DNA and proteins. It has also been used to treat a blood disorder called polycythemia vera and certain types of leukemia, but it is not commonly used anymore.
How are isotopes used in medicine?
Medical isotopes are used by medical professionals to diagnose and treat health conditions such as heart disease and cancer. The production of medical isotopes is achieved by using two overarching technologies: nuclear reactors, and particle accelerators (linear accelerators, cyclotrons).
What is radioactive decay biology?
radioactive decay. (Science: physics) The process by which a spontaneous change in nuclear state takes place. This process is accompanied by the emission of energy in various specific combinations of electromagnetic and corpuscular radiation and neutrinos.
What are the five applications of isotopes?
- An isotope of uranium is used in nuclear plants.
- An isotope of cobalt is used to treat cancer.
- An isotope of iodine is used to treat goitre.
Why are radioactive isotopes used on animals?
Isotopes are used to identify those breeds and strains which are immunologically better able to cope with the challenge and those least affected by the parasitic infestation in terms of either blood loss or damage (depressed protein levels and low red cell counts).
Which radioactive isotope is used for food preservation?
The two most common sources of high-energy radiation used in the food industry are cobalt-60 (60Co) and cesium-137 (137Cs).
What are 3 examples of isotopes?
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.
