Radiocarbon Dating. WebWell, not really. There 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. northerners in small berths
