Positron Emission, Metabolic Activity, Detection, "short" physical half-life
The principle behind the use of radioactive tracers is that an atom in a chemical compound is replaced by another atom, of the same chemical element. The substituting atom, however, is a radioactive isotope. This process is often called radioactive labeling.
A trackable isotope is a radioactive atom that can be followed through biological processes using imaging techniques like positron emission tomography (PET) or autoradiography. These isotopes can be used to understand how certain molecules or substances are taken up, metabolized, or distributed within living organisms.

A radioactive tracer is a small amount of radioactive material that can be injected into the body, where it accumulates in specific tissues or organs. In the case of tumors, the tracer is often designed to target cancerous cells that have increased metabolic activity. When scanned with imaging techniques like PET (positron emission tomography), the tracer emits radiation that is detected, allowing doctors to visualize the location and size of the tumor. This method helps in diagnosing cancer and guiding treatment decisions.
yes it does. the chemical behavior of a radioactive isotope is essentially the same as that of the stable isotopes of an element. When you have the addition of a small quanity of radioactive isotope, it becomes a tracer, which traces molecular changes. (look up the Melvin Calvin experiment for more help)
The isomer Tc-99m is largely used as tracer for radiodiagnostic.The isotope Tc-99 is used to make standardized beta emitter sources.Technetium has useful properties but it is difficult to be used in other fields of technology because is radioactive.

its a non medical tracer.
The term "210Bi" refers to the isotope bismuth-210, which is a radioactive isotope of the element bismuth. It has a half-life of about 5 days and is produced through the decay of polonium-210. Bismuth-210 is used in various applications, including medical research and as a tracer in environmental studies. Its radioactivity makes it important in understanding certain decay processes and radiation exposure.
A radioactive tracer is a radioactive atom inserted in a compound to see what happens to it in a reaction, usually in biotechnology. For example, to find out where carbon atoms go in photosynthesis, scientists can give the plants carbon dioxide with carbon-14 instead of carbon-12 and track the progress of the carbon-14.
They dissolve it in a liquid and the patient drinks it

Polonium isotopes are not used as tracers.
