It is recommended that archaeologists, or any client in general, ask the laboratory if results have systematic or random errors.

The year was chosen because it was the standard astronomical epoch at that time. Some samples, like wood, already ceased interacting with the dating and have online dating sites mackay apparent age at death and linking them to the age of the deposits around the sample would not be wholly accurate.

So for anything younger than AD or so carbons often do not give an age but the raw radiocarbon measurement as percent of the standard. Laboratories have limitations in terms of the samples they can process for radiocarbon dating.

However, a major disadvantage with using BP is--the present year, of course, changes every twelve months. Trees maintain and record carbon 14 equilibrium in their growth ringsā€”and some of those trees produce a ring for every year they are alive; the study of dendrochronologyalso known as tree-ring dating, is based on that fact of nature.
