The ratio between these isotopes begins to change after a plant or animal dies[2]. So the length of time since the plant or animal died is determined by measuring the relative concentrations of the isotopes[3]. Carbon dating only works back about 50,000 years because, for older samples, there's not enough C14 for accurate measurements.

Yes, there are a lot of details and sources of variation, like different isotope ratios in different places and at different times in the past.

The C14 method has been and continues to be applied and used in many, many different fields including hydrology, atmospheric science, oceanography, geology, palaeoclimatology, archaeology and biomedicine.

All plants and animals on Earth are made principally of carbon.

It’s astonishing how much information exists about organizations dedicated to worthy causes. Some friends and I recently hiked into Texas’ Palo Duro Canyon, where sedimentary rock layers span the horizon.

A Google search on charitable giving will produce countless websites.

The radiocarbon method was developed by a team of scientists led by the late Professor Willard F.

Libby of the University of Chicago after the end of World War 2.

Today, there are over 130 radiocarbon dating laboratories around the world producing radiocarbon dates for the scientific community.

It is called 'radio'-carbon, because it is 'radioactive'.

This means that its atomic structure is not stable and there is an uneasy relationship between the particles in the nucleus of the atom itself.

After the war he became very interested in peaceful applications of atomic science.

He and two students first measured the "half-life" of radiocarbon.

During the period of a plant's life, the plant is taking in carbon dioxide through photosynthesis, which is how the plant makes energy and grows.
