Method of radioactive dating turin shroud
In the 1940s, scientists succeeded in finding out how long it takes for radiocarbon to disappear, or decay, from a sample of carbon from a dead plant or animal.
In Nyerup's time, archaeologists could date the past only by using recorded histories, which in Europe were based mainly on the Egyptian calendar.
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.
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.
