Carbon dating and its effects
Thus, it dilutes the activity of the lake meaning that the radioactivity is depleted in comparison to 14C activity elsewhere.
The lake, in this case, has a different radiocarbon reservoir than that of the majority of the radiocarbon in the biosphere and therefore an accurate radiocarbon age requires that a correction be made to account for it.
"Everything which has come down to us from heathendom is wrapped in a thick fog; it belongs to a space of time we cannot measure.
We know that it is older than Christendom, but whether by a couple of years or a couple of centuries, or even by more than a millenium, we can do no more than guess." [Rasmus Nyerup, (Danish antiquarian), 1802 (in Trigger, 19)].
Radiocarbon dating has been helping put the planet’s history in the right order since it was first invented in the 1940s, giving scientists a key way to determine the age of artifacts like the Dead Sea Scrolls and the Shroud of Turin.
Thanks to fossil fuel emissions, though, the method used to date these famous artifacts may be in for a change.
Those concerned with climate change spend a lot of time arguing that it’s not just an environmental problem, but also an economic, human rights, national security, and even mental health issue.
Now a new study has found that greenhouse gas emissions could impact a range of unlikely fields due to their effect on radiocarbon dating, a much-heralded scientific method used to determine the age of objects containing organic material.The study, published Monday in the , found that emissions from fossil fuels are artificially raising the carbon age of the atmosphere, which makes objects today seem much older than they are when scrutinized by a radiocarbon dater.This change in the ability to date objects could impact measurements commonly taken in a broad range of endeavors, including archaeology, forgery detection, forensics, earth science, and physiology.The radiocarbon method was developed by a team of scientists led by the late Professor Willard F.Libby of the University of Chicago in immediate post-WW2 years.[A Conventional Radiocarbon Age or CRA, does not take into account specific differences between the activity of different carbon reservoirs.
