Number 14 carbon 14 dating denotes amount
When the neutron collides, a nitrogen-14 (seven protons, seven neutrons) atom turns into a carbon-14 atom (six protons, eight neutrons) and a hydrogen atom (one proton, zero neutrons).
Carbon-14 is radioactive, with a half-life of about 5,700 years.
No other scientific method has managed to revolutionize man’s understanding not only of his present but also of events that already happened thousands of years ago.
Archaeology and other human sciences use radiocarbon dating to prove or disprove theories.
For more information on cosmic rays and half-life, as well as the process of radioactive decay, see How Nuclear Radiation Works.
The carbon-14 atoms that cosmic rays create combine with oxygen to form carbon dioxide, which plants absorb naturally and incorporate into plant fibers by photosynthesis.
The age of a piece of antique can be determined by its style in certain period, the age of fossil is related to the stratification etc.
CARBON-14 IS CREATED (Figure 1a): When cosmic rays bombard the earth’s atmosphere, they produce neutrons.
These excited neutrons then collide with nitrogen atoms in the atmosphere, changing them into radioactive carbon-14 atoms.
In this case, it is observed that the mass of fired-clay ceramics, brick, tile etc. The subsequent re-absorption of moisture from the environment produces water mass gain, which is found to follow a power law of the time after the initial heating.
This dating method is still under development following its introduction in early 21st century.
For example, every person is hit by about half a million cosmic rays every hour.
