In this example, you would divide -0.223143551 by 2, the number of hours, … WebbThere are many many isotopes which decay more slowly. The reason C-14 is used for dating is that due to its medium half-life (not long nor short), C-14 in the environment is in a state of homeostasis - constantly decaying and being renewed, such that the overall amount remains the same.
