What is the effective range of radiocarbon dating

Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers.Carbon-14 dating has been used successfully on the Dead Sea Scrolls, Minoan ruins and tombs of the pharaohs among other things. The half-life of carbon-14 is approximately 5,730 years. dinosaurs the evolution alleges lived millions of years ago.^ Ranges reflect varying carbon content (weights approximate).Sample standard errors will increase as radiometric samples size decreases (see Table 2).

They are chronographs, recording clocks, by which the succeeding seasons are set down through definite imprints," he wrote in the pages of National Geographic.A wide range of sample types can be submitted for dating.We can advise on the suitability of different materials and the most effective pretreatments.When researchers find a bone or artifact, how do they know how old it is?While there are a number of answers to that question, most of which depend largely on the age and surroundings of the item, carbon dating is surely one of the most important.
