Radioactive isotopes are used is:
- medicine, for treatment by irradiation
- medicine, for diagnostic
- in science/technology as tracers
- as source of energy
- as source of ionizing radiations
- in many instruments
- determination of rocks age
etc.
Not all isotopes are radioactive; the radioactive isotopes are unstable and emit radiations.
Two examples are: carbon-14 and cobalt-60.
Both isotopes and radioactive isotopes are pretty much the same but radioactive isotopes are better because it can be used to make medicine.
Radioactive isotopes are not stable.
Sodium has no radioactive isotopes.
All the uranium isotopes are radioactive.
All radioactive isotopes will disintegrate.
The property of isotopes that allows radiotracers to be useful in studying chemical reactions is their ability to emit radiation, which can be detected and tracked. By substituting a stable isotope with a radioactive isotope in a molecule, researchers can track the movement and transformation of the molecule during a chemical reaction by measuring the emitted radiation.
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.
All isotopes of francium are radioactive.
radioactive isotopes! :)
Some examples are deuterium and tritium which are radioactive isotopes of hydrogen.
