What does radiolabeled mean?
Radiolabeled refers to substances or molecules that have been marked with radioactive isotopes, enabling researchers to track their movement, metabolism, or interaction with other molecules. This technique is invaluable in various scientific applications, including medical research, diagnostics, and therapeutic development. By incorporating radioactive isotopes into compounds, scientists can study their behavior, distribution, and effects in living organisms or in vitro systems. The use of radiolabeled compounds has significantly advanced our understanding of biological processes and has led to the development of novel treatments for various diseases.

Etymology of radiolabeled
The term 'radiolabeled' is derived from the combination of 'radio-' referring to radioactive isotopes, and '-labeled' meaning marked or tagged. The concept of labeling substances with radioactive isotopes dates back to the early 20th century, when scientists began exploring the properties of radioactive elements. The term 'radiolabeled' itself emerged as a convenient shorthand to describe substances marked with radioactive isotopes for research purposes.
