Educational Research Center. Paper presentation. 2020-07-26 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). 2.4.1 Isotopes and Their Uses . 2.5 The Structure of Atom - Practices .

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). The isotopes 39 K and 41 K are stable isotopes; however, the isotope 40 K is a radioisotope that decays with a half-life of 1.26 × 10 9 years. Since the naturally occurring isotopes are remnants of the nucleosynthesis of the Earth, which is 2.54 × 10 9 years old ( Dalrymple, 2001 ), the isotope 40 K has had time to decay since the Earth's creation.
