Editor’s note: This is part of a series called “The Day Tomorrow Began,” which explores the history of breakthroughs at UChicago. Learn more here. Radiocarbon dating, or carbon-14 dating, is a ...
In 1940 Martin Kamen discovered radioactive carbon-14 (an isotope of carbon) and found that it had a half-life of about 5,700 years. Scientists had also found that some of the nitrogen in the ...
Radiocarbon dating, also known as carbon-14 dating, is a method to determine the age of organic materials as old as 60,000 years. First developed in the 1940s at the University of Chicago by Willard ...
Andrew Smith, Dr. Quan Hua and Dr. Bin Yang have contributed to a paper that elucidates how in situ cosmogenic radiocarbon (14 C) is produced, retained and lost in the top layer of compacting snow ...
In order to determine how “old” this dissolved organic carbon is, its natural radiocarbon activity has been measured for two deep-water samples taken off southern California.
SEVERAL articles 1–3 have described efforts to reconcile radiocarbon ages with “true ages”. The principle behind these procedures lies in the determination of a radiocarbon age and its ...
"Having realised this we have developed a new instrument technology around putting carbon-14 through camping gas. " Dr Shanks says PIMS will take radiocarbon dating out of specialist centres and ...
So what's the story behind radiocarbon dating ... and seeds by finding out how much carbon-14 is left in the remains. Check it out for yourself. At the very least you'll find out what it's ...
Radiocarbon-based analyses can now accomplish sufficient resolution for meaningful independent estimates of Inka chronology, however, and it is incumbent upon archaeologists to develop such appraisals ...
Radiocarbon dating is one of the key discoveries of the twentieth century. Archaeologists have recently begun to employ high precision radiocarbon dating to explore the chronology of the Iron Age in ...
