How far back does carbon dating work
When the plant or click the following article that consumed the foliage dies, it stops exchanging carbon with the environment and from there on in it is simply a case of measuring how much carbon 14 has been emitted, giving its age. The carbon forms at a rate which appears to be constant, so that by measuring the radioactive emissions from once-living matter and hiw its activity with the equilibrium how far back does carbon dating work of living things, a measurement of the time elapsed can be made. One can count atoms of different masses with a mass spectrometerbut that is problematic for carbon dating because of the low concentration of carbon and the existence of nitrogen and CH 2 which have essentially the same mass. To test this oversight, the researchers measured a series of carbon 14 ages in southern Jordan tree rings calculated as being from between and How far back does carbon dating work CO 2 is used in photosynthesis ddoes plants, and from here is passed through the food chain see figure 1, below.
