Half-lives range from fractions of a second to billions of years. For example, Carbon-14 (C-14), a naturally occurring radionuclide, has a half-life of 5,730 years. After this amount of time passes, half of the initial amount of C-14 is present. Therefore, if you began with two (2) curies of C-14, one-half of that amount, or one curie, would be present 5,730 years later.
