Quizplus · Accepted Answer

All of the options listed are true. Radioactive isotopes have the same chemical properties as nonradioactive isotopes, which allows them to be used as tracers without interfering with the normal reactions they participate in. It is easy to follow the movement of radioactive isotopes because they emit radiation that can be detected. The decay products produced from the radioactive decay can also be detected, which provides information about the location and movement of the tracer.
