Carbon dating artifacts dating kontakti
Carbon-14 dating can be used on objects ranging from a few hundred years old to 50,000 years old.
Libby and others (University of Chicago) devised a method of estimating the age of organic material based on the decay rate of carbon-14.
There is a greater part of man’s unwritten past that archaeology has managed to unravel.
Studying the material remains of past human life and activities may not seem important or exciting to the average Joe unlike the biological sciences.
Green plants absorb the carbon dioxide, so the population of carbon-14 molecules is continually replenished until the plant dies.

Archaeology has undoubtedly enriched mankind’s history like no other science.
Love-hungry teenagers and archaeologists agree: dating is hard.How do scientists know how old an object or human remains are?What methods do they use and how do these methods work?After death the amount of carbon-14 in the organic specimen decreases very regularly as the molecules decay.Carbon-14 has a half-life of 5,730 ± 40 years, meaning that every 5,700 years or so the object loses half its carbon-14.
