These isotopes are stable, which is why they are with us today, but unstable isotopes are also present in minute amounts.

About one carbon atom in a trillion (10) contains a radioactive nucleus with 6 protons and 8 neutrons — carbon 14.

C like they absorb other isotopes of carbon — through the respiration of carbon dioxide — and then use this carbon to produce sugars, fats, proteins, and vitamins.By 1965, atmospheric C concentrations were double their pre "atomic age" values.Coal and petroleum are the fuels that powered the Industrial Revolution.Serious technicians know how to compensate for this preference when dating samples.) With a half life of 5730 years, C in a piece of living organic matter will be the same as it is in the atmosphere but larger than in a piece of dead organic material.A timber found in a home built 5730 years ago (one half life) would have half the C in the Earth's atmosphere has remained constant.
