radioactive tracers
Trackable medical markers
Radioactive tracers are substances containing radioactive isotopes introduced into a system to track movement or processes.
In medicine, tracers injected into the body reveal blood flow, organ function, or tumor locations through detectable radiation.
In research, they follow chemical pathways through organisms or environmental systems: Radioactive tracers showed how carbon moves through the food chain.
