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.
The ideal properties of a radioactive isotope used as a medical tracer include a suitable half-life for the imaging procedure, emission of detectable radiation, minimal impact on biological tissues, and easy incorporation into the target compound. Additionally, it should decay by a mode that minimizes exposure to harmful radiation.

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.
An isotope that contains two neutrons in its nucleus is deuterium, also known as hydrogen-2. Deuterium is a stable isotope of hydrogen that has one proton, one electron, and two neutrons. It is commonly used in nuclear reactors and as a tracer in chemical reactions.

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)

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.

Compared to 31P, the radioactive isotope 32P has an additional neutron in its nucleus, making it unstable and radioactive. This extra neutron causes 32P to decay at a faster rate, emitting beta particles in the process. Due to its radioactivity, 32P is often used in biological research as a tracer for studying biochemical processes.
About 1 Mg.
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.
