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.
A knowledge of radioactive half-life is important because. It enables the dating of artifacts. It allows us to calculate how long we must store radioactive waste until they become safe. It enables doctors to use safe radioactive tracers. Half-life is the time it takes for one-half of the atoms of a radioactive material to disintegrate. Scientists can use the half-life of carbon-14 to determine the approximate age of organic objects. They determine how much of the carbon-14 has transformed. They can then calculate the age of a substance.
