radioactive elements, tracers, are used in molecular research to investigate the movement of atoms and molecules through a biological system.
At various intervals the movement of the radioactive atoms can be traced using photographic film.
They are an established part of biomedical research.
Radioactive isotopes are a subset of isotopes. If we look at all isotopes, some of them are radioactive. That means that they have unstable nuclei, and they will decay spontaneously sooner or later.
Radioactive isotopes are isotopes of an element that have an unstable nucleus, causing them to emit radiation as they decay. One example of a radioactive isotope is carbon-14, which is commonly used in carbon dating to estimate the age of ancient artifacts or fossils.
Isotopes are used to determine the age of rock.
Radioactive phosphorus is used to treat abnormal cell proliferation, e.g., polycythemia (increase in red cells) and leukemia (increase in white cells). Radioactive iodine can be used in the diagnosis of thyroid function and in the treatment of hyperthyroidism. Since the iodine taken into the body concentrates in the thyroid gland, the radioaction can be confined to that organ. In research, radioactive isotopes as tracer agents make it possible to follow the action and reaction of organic and inorganic substances within the body, many of which could not be studied by any other means. They also help to ascertain the effects of radiation on the human organism (see radiation sickness ). In industry, radioactive isotopes are used for a number of purposes, including measuring the thickness of metal or plastic sheets by the amount of radiation they can stop, testing for corrosion or wear, and monitoring various processes.
They are an established part of biomedical research.

Elements that decay (give off protons and neutrons) to form other elements. *It's not elements as such that are stable or unstable, but rather isotopes. Even elements of small atomic number have unstable isotopes that undergo radioactive decay, for example carbon-14. Elements with higher atomic numbers than Lead (82) are naturally radioactive in all isotopes. Bismuth (83) has an extremely long half-life, but the time generally becomes shorter (the decay more rapid) as the size of the nucleus gets progressively larger for heavier radioactive elements.
Texas Biomedical Research Institute was created in 1941.
