Simple definition of carbon 14 dating
Radioactive decay can be used as a “clock” because it is unaffected by physical (e.g. For instance, the amount varies according to how many cosmic rays reach Earth.
This is affected by solar activity and the earth’s magnetic field.
In addition, samples need to be thoroughly cleaned to remove carbon contamination from glues and soil before dating.
This is particularly important for very old samples.
Moving away from techniques, the most exciting thing about radiocarbon is what it reveals about our past and the world we live in.
Radiocarbon dating was the first method that allowed archaeologists to place what they found in chronological order without the need for written records or coins.
Radiocarbon dates are presented in two ways because of this complication.
The uncalibrated date is given with the unit BP (radiocarbon years before 1950).
The barbarians of the north were capable of designing complex structures similar to those in the classical world.
Luckily, we can measure these fluctuations in samples that are dated by other methods.
Tree rings can be counted and their radiocarbon content measured.
Professor Willard Libby produced the first radiocarbon dates in 1949 and was later awarded the Nobel Prize for his efforts.
Radiocarbon dating works by comparing the three different isotopes of carbon.
The total mass of the isotope is indicated by the numerical superscript.
