Sealed radioactive sources are used in industrial radiography, gauging applications, and mineral analysis. The attributes of naturally decaying atoms, known as radioisotopes, give rise to their multiple applications across many aspects of modern day life (see also information paper on The Many Uses of Nuclear Technology ). For example, technetium-99m, one of the most common medical isotopes used for imaging studies, has a half-life of 6 hours. The short half-life of technetium-99m helps keep the dose to the patient low.

Radioactive isotopes examples

These isotopes are radioactive in nature and are, therefore, known as radioisotopes (or radionuclides). Examples of radioactive isotopes include carbon-14, tritium (hydrogen-3), chlorine-36, uranium-235, and uranium-238. Some isotopes are known to have extremely long half-lives (in the order of hundreds of millions of years). (a) Those isotopes which are unstable due to the presence of extra neutrons in their nuclei and emit various types of radiations are called radioactive isotopes. The radiations emitted are in the form of alpha particles, beta particles and gamma rays.

The radiations emitted are in the form of alpha particles, beta particles and gamma rays. Common examples of radioactive isotopes are Arsenic−74, Iodine−131 and Cobalt−60.

Isotope Example 3 | Science, 2020-08-14 · Radioactive isotopes of radium, thorium, and uranium, for example, are found naturally in In the periodic arrangement table, you can see an element that emits radiation called a radioactive element, or that does not emit a radiation called a stable element. For example, iodine with mass number 129 or 131 to 135 is a radioactive element. Radioactive elements are also called radioactive isotopes.

Only a limited number of radioisotopes can be used in biological research because they must meet specific qualifications. Most importantly, they have to be elements that naturally occur in the experimental system.
