Radiocarbon dating is one of the most widely used scientific dating methods in archaeology and environmental science.It can be applied to most organic materials and spans dates from a few hundred years ago right back to about 50,000 years ago - about when modern humans were first entering Europe.When those plants, the animals that ate them, and the animals' predators die, they stop consuming the C14 isotope, which decays to half its original amount in about 5730 years.
And carbon-14 is constantly doing this decay thing. So over the course of 5,730 years, roughly half of them will have decayed. Well, if you know that all living things have a certain proportion of carbon-14 in their tissue, as kind of part of what makes them up, and then if you were to find some bone-- let's just say find some bone right here that you dig it up on some type of archaeology dig.A child mummy is found high in the Andes and the archaeologist says the child lived more than 2,000 years ago.How do scientists know how old an object or human remains are?Cosmic radiation generates neutrons in the atmosphere, which split nitrogen 14 into hydrogen and carbon 14.Plants consume carbon dioxide, including small quantities of radioactive C14 atoms.This one is dedicated to Susan Gerbic and her team of wikipedia editors, fighting the good fight against facts claimed without references. You mean that somebody just made up all that stuff about them? Since last January we’ve been bringing science programming to bars, theaters, and comic cons in Colorado.
