extramarital dating sites - Radiocarbon dating how stuff works
This is only because it is well calibrated with objects of known age.
I recently shared a story that included radiocarbon dating.
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.

Over the years, carbon 14 dating has also found applications in geology, hydrology, geophysics, atmospheric science, oceanography, paleoclimatology and even biomedicine.
Radiocarbon, or carbon 14, is an isotope of the element carbon that is unstable and weakly radioactive. Carbon 14 is continually being formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen 14 atoms.
When an organism dies, it stops absorbing carbon-14, which then begins to decay.
By measuring how much carbon-14 still remains in an organic compound, you can calculate how old it is.
Carbon-14 is constantly being formed in the atmosphere as cosmic rays interact with nitrogen gas, and it gets absorbed by every living thing on Earth.
Because carbon-14 is mildly radioactive, it has a specific half-life (rate of decay).
Bone is also porous, so fluids and microbes can penetrate and destroy the precious collagen over time. German scientists conducted systematic research to identify optimal preservation criteria for bone mineral in archaeological bones.Tags: Adult Dating, affair dating, sex dating
