Radio carbon dating how does it work

The latest curves were ratified at the 21st International Radiocarbon Conference in July of 2012.

Within the last few years, a new potential source for further refining radiocarbon curves is Lake Suigetsu in Japan.

It takes about 5,730 years for half of a sample of radiocarbon to decay back into nitrogen.

It takes another 5,730 for half of the remainder to decay, and then another 5,730 for half of what's left then to decay and so on.

But there are many misconceptions about how radiocarbon works and how reliable a technique it is.The new isotope is called "radiocarbon" because it is radioactive, though it is not dangerous.It is naturally unstable and so it will spontaneously decay back into N-14 after a period of time.The half-life of an isotope like C14 is the time it takes for half of it to decay away: in C14, every 5,730 years, half of it is gone.So, if you measure the amount of C14 in a dead organism, you can figure out how long ago it stopped exchanging carbon with its atmosphere.
