radioactive tracer

[¦rād·ē·ō′ak·tiv ′trā·sər]
(nucleonics)
A radioactive isotope which, when attached to a chemically similar substance or injected into a biological or physical system, can be traced by radiation detection devices, permitting determination of the distribution or location of the substance to which it is attached. Also known as radiotracer.

They measured the RTD in a copper ore thickening, filtration, and drying system using 1GBq of Cu-64 as the radioactive tracer. The RTD study shows the presence of a dead zone and bypasses, which affect the efficiency of the dewatering system, and provides a detailed analysis of the solid state behaviour inside the dewatering subsystems.

Dr Mark Hughes, clinical director for imaging services, said: "Patients are injected with small amounts of radioactive tracer, similar in consistency to sugar.
In a PET scan, patients are given a solution of sugar tagged with a radioactive tracer. When the sugar reaches the brain, it congregates in metabolically active areas that "light up" on scans.
They labeled the dye with a commonly used radioactive tracer and used a PET scanner to directly see plaque in a living person's brain.
In the past few decades, whole new areas of thought and exploration have been opened up by the sciences--by electronics, by astrophysics, by microbiology, by the study of nucleoproteins and their role in genetics, by radioactive tracer studies, and by nuclear physics.
