The rate of. decay is a fixed rate called a half-life. The half-life of a radioactive isotope refers to the amount of time. required for half of a quantity of a radioactive isotope to decay. Carbon-14 has a half-life of 5,730 years, which means that if. you take one gram of carbon-14, half of it will decay in 5,730. years. Different isotopes have different half-lives.
radioactive isotope. n. An isotope having an unstable nucleus that decomposes spontaneously by emission of a nuclear electron or helium nucleus and radiation, thus achieving a stable nuclear composition. chemical element having the same atomic number as another (i.e. the same number of nuclear protons), but having a different atomic mass (i.e. a different number of nuclear neutrons). radioactive isotope. one having an unstable nucleus and which emits characteristic radiation during its decay to a stable form.
