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.
Different types of radioactive materials have different decay times, varying from fractions of a second to millions of years. Each radioactive material has a decay rate. The time that it takes for half of the radioactive atoms to decay is called a half-life. For example, the previously mentioned technetium-99m has a half-life of six hours which means that, starting with 100 percent, after six hours, we will have 50 percent left.
