Radioactive isotopes used carbon dating Teen web cams adult

In 1946, Willard Libby proposed an innovative method for dating organic materials by measuring their content of carbon-14, a newly discovered radioactive isotope of carbon.

Theoretically, if one could detect the amount of carbon-14 in an object, one could establish that object’s age using the half-life, or rate of decay, of the isotope.

In 1946, Libby proposed this groundbreaking idea in the journal Physical Review.

Libby cleverly realized that carbon-14 in the atmosphere would find its way into living matter, which would thus be tagged with the radioactive isotope.is a technique used by scientists to learn the ages of biological specimens – for example, wooden archaeological artifacts or ancient human remains – from the distant past.It can be used on objects as old as about 62,000 years.Scientists look at half-life decay rates of radioactive isotopes to estimate when a particular atom might decay.A useful application of half-lives is radioactive dating.
