Carbon 14 radioisotope dating Free adult phone sex chat lines
Until this century, relative dating was the only technique for identifying the age of a truly ancient object.By examining the object's relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site.It has been determined that the rate of radioactive decay is first order.
Radiocarbon dating involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content.
In this equation, the units of measure for N and No can be in grams, atoms, or moles.
It does not matter as long as they are like measures.
A very small percentage of carbon, however, consists of the isotope carbon 14, or radiocarbon, which is unstable.
Carbon 14 has a half-life of 5,780 years, and is continuously created in Earth's atmosphere through the interaction of nitrogen and gamma rays from outer space.
