Radioactive isotopes are used in medicine (treatment or diagnostic), as tracers in hydrogeology, physiology, sources of energy, standards for radiation, sterilization, radioactive dating, etc.
Not all isotopes are radioactive; the radioactive isotopes are unstable and emit radiations.
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.
All isotopes of francium are radioactive.
radioactive isotopes! :)
Some examples are deuterium and tritium which are radioactive isotopes of hydrogen.
No, Barium has both stable and radioactive isotopes. Out of its 25 known isotopes, only 6 of them are considered radioactive. The most stable isotope of Barium is Barium-138, which is not radioactive.
Not all of the transition elements are radioactive. Many of them are, and some of them have common radioactive isotopes, but some of them have no naturally occurring radioactive isotopes. Please note that all elements have synthetic radioactive isotopes, at least.
Silver itself is not radioactive. However, certain isotopes of silver can be radioactive. For example, silver-108 and silver-110 are radioactive isotopes with long half-lives that can undergo radioactive decay. These isotopes are not commonly found in nature.
