pharmaceutical drugs that are radioactive). Radiopharmaceuticals are used in the field of nuclear medicine as radioactive tracers in medical imaging and in...

does not vary due to radioactive decay). Stable isotope labeling involves the use of non-radioactive isotopes that can act as tracers used to model several...

by injecting a radioactive tracer into a peripheral vein usually in arms and then following the path of tracer by camera as the tracer moves to lungs...

would be inappropriate to proceed with injecting the patient with the radioactive tracer. When the benefit does justify the procedure, then the radiation exposure...

chemical tracer which is attracted to or concentrated by the activity which is being studied. That chemical tracer incorporates a short lived radioactive isotope...

This isotope has also found use in nuclear weapons research and as a radioactive tracer in hydrological research. 198Au was possibly observed for the first...

containing gamma-emitting tracer isotopes is used to trace and measure fractures.[citation needed] A 1995 study found that radioactive tracers were used in over...

Radioactive sources are used for logging formation parameters. Radioactive tracers, along with the other substances in hydraulic-fracturing fluid, are...
