Headquartered in Miami, Florida, Beta Analytic provides biobased content / renewable carbon measurements to top commercial organizations, government agencies, scientists and engineers.BETA has been the world leader in Carbon-14 analyses since 1979 and has unmatched expertise analyzing complex samples.What methods do they use and how do these methods work?In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.This carbon-14 immediately starts to radioactively decay but is constantly being recreated.
From that time forward, the only process at work in the body is radioactive decay. You probably have seen or read news stories about fascinating ancient artifacts.At an archaeological dig, a piece of wooden tool is unearthed and the archaeologist finds it to be 5,000 years old.Animals eat plants and/or other animals; humans eat plants and animals.Therefore all living plants, animals, and human beings have the same amount of carbon-14 in their bodies at the same time.
Carbon-14 originates in the upper atmosphere of the earth and is created when neutrons originating from solar radiation bombardment collide with nitrogen in the air.
