Isotopes used in radiocarbon dating a report on digital dating in canada
Carbon-14 is continually produced in the upper atmosphere as neutrons, which are by-products of cosmic rays, and is then absorbed by nitrogen atoms.
Carbon-14 atoms react with oxygen to form carbon dioxide, and carbon-14 is incorporated into the food chain when plants use carbon dioxide for photosynthesis.

The carbon-14 bomb spike has helped researchers to date Antarctic mosses (pictured above), trees and may be useful for dating human remains, such as teeth, to help identify victims of homicide or mass disasters.
In 2010, Purdue University published a research paper stating that their researchers had detected slight fluctuations in radioactive isotope decay rates "in synch with the rotation of the sun's core." The article also stated: Has there been any further research on this, and has it been found to affect carbon dating techniques or other archeological dating methods? Graven, "Impact of fossil fuel emissions on atmospheric radiocarbon and various applications of radiocarbon over this century," Proceedings of the National Academy of Sciences 112.31 (2015): 9542-9545.
Researchers can find out how long ago something died using radiocarbon dating.
Bones and teeth from animals and humans, as well as artefacts made out of wood, fabric or paper are just some of the objects that can be aged using this process.
Radiocarbon dating can date samples up to 50,000 years old.
Samples older than that contain so little carbon-14 that the dating process is inaccurate.
Very good scientists listen to their inner crackpot but keep it inside until they are very sure that their inner crackpot has revealed something new.
Not so good scientists regularly expose their inner crackpot for the whole world to see.
So the net effect on archeological dating would be null even if these variations existed.Tags: Adult Dating, affair dating, sex dating
