Polonium isotopes are not used as tracers.
It is called a tracer

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)

Deuterium is an isotope of hydrogen. It has one proton and one neutron in its nucleus, compared to regular hydrogen which has only one proton. Deuterium is slightly heavier than regular hydrogen and is often used in laboratory experiments and as a tracer in scientific studies.
In general a tracer is a substance that can be used e.g. to monitor how a process runs or a volume of material is transported in a medium. The tracer is part of the system that is inspected. Anything can be taken as tracer which is suitable to monitor these processes closely and whose specific property (isotopic ratio, concentration, colour etc.) can be measured sufficiently precisely to allow for a sound interpretation of experimental results. Isotopic tracers can for example be used to monitor how groundwater flows in an aquifer, but for the same purpuses one can also use elemental or molecular tracers.
It's being studied for potential use in nuclear medicine (the isotope astatine-211).
Cisco Packet Tracer is a powerful network simulation program that allows students to experiment with network behavior and ask “what if” questions. As an integral part of the Networking Academy comprehensive learning experience, Packet Tracer provides simulation, visualization, authoring, assessment, and collaboration capabilities and facilitates the teaching and learning of complex technology concepts.
in the 1.9 liter engine it should be from 35-45 psi
The gap should be .052-.056
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.
