A child mummy is found high in the Andes and the archaeologist says the child lived more than 2, years ago. How do scientists know how old an object or human remains are? 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 dating. Carbon dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50, years old.
Can radioactive carbon dating be used to determine the age of dinosaur fossils why or why not

Carbon dating , known also as radiocarbon dating , is a method for determining the age of an object containing organic material by using the properties of radionuclide carbon In spite of this short half-life compared to the age of the earth, carbon is a naturally occurring isotope. Its presence can be explained by the following simple observation. Our atmosphere contains many gases, including nitrogen Besides, the atmosphere is constantly bombarded with high energy cosmic rays , consisting of protons, heavier nuclei, or gamma rays.

Radiometric dating or radioactive dating is any technique used to date organic and also inorganic materials from a process involving radioactive decay. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. All these methods are based on the fact the rate at which radioactive nuclei disintegrate is unaffected by their environment, it can be used to estimate the age of any material sample or object which contains a radioactive isotope. Calculations of the decay of radioactive nuclei are relatively straightforward, owing to the fact that there is only one fundamental law governing all decay process.
