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.
Isotopes: All of the isotopes of rutherfordium are radioactive. The most stable isotope, Rf-267, has a half-life around 1.3 hours. Sources of Element 104: Element 104 has not been found in nature. It is only produced by nuclear bombardment or decay of heavier isotopes.
