Sep 13,  · (n.) the determination of the age of objects of organic origin by measurement of the radioactivity of their carbon content. - I Know What It Means But I Don't Exactly Know How To Use It In A Sentence?Status: Resolved. Looking for sentences with 'carbon dating'? Here are some examples. Radiocarbon dating (also referred to as carbon dating or carbon dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon (14 C), a radioactive isotope of carbon. The method was developed by Willard Libby in the late s and soon became a standard tool for archaeologists.

Carbon dating sentences -

The low activity of the carbon limits age determinations to the order of 50, years by counting techniques. Carbon only works on organisms that take in carbon-dioxide living things. Corrected dates bring the difference in age approximately within the life span of an ox. Sign up today and start improving your vocabulary! At equilibrium with the atmosphere, a gram of carbon shows an activity of about 15 decays per minute. This instability makes it radioactive. I'm no scientist but to the best of my knowledge, carbon can never decay completely. Carbon dating is mainly used by archaeologists to date recent finds as the technique is carbon dating sentences accurate for 50, to 60, years in the past. The counters are surrounded by lead or steel shielding, to eliminate background radiation and to reduce the incidence of cosmic rays. In the s samples were tested with AMS, yielding uncalibrated dates ranging from 11, BP to 11, BP, both with a standard error of years. Measurement of the amount of radioactive carbon remaining in the material thus gives an estimate of its age. Fossils older than 50, years may have an undetectable amount carbon dating sentences 14 C.
