Additional complications come from the burning of fossil fuels such as coal and oil, and from the above-ground nuclear tests done in the 1950s and 1960s.For decades, radiocarbon dating has been a way for scientists to get a rough picture of when once-living stuff lived.

Dendrochronology and radiocarbon dating have intertwined histories, she explains, with roots firmly planted at the UA.The resulting radiocarbon combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died.The older a sample is, the less (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to around 50,000 years ago, although special preparation methods occasionally permit accurate analysis of older samples.In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old.Few people who claim that radiometric dating proves the earth is billions of years old really understand the underlying assumptions. Snelling examines these assumptions and equips viewers with information to counter the anti-biblical arguments.
