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.
Plutonium-238 has a half-life of 88 years and emits alpha particles. It is a heat source in radioisotope thermoelectric generators, which are used to power some spacecraft. Plutonium isotopes are expensive and inconvenient to separate, so particular isotopes are usually manufactured in specialized reactors.lutonium-238 has a half-life of 88 years and emits alpha particles.
