Let me make it clear about Explainer: what’s radiocarbon dating and exactly how does it work?
Dating history
When residing things die, muscle isn’t any longer being changed as well as the radioactive decay of 14 C becomes apparent. Around 55,000 years later on, so much 14 C has decayed that what continues to be can no further be calculated.
Radioactive decay may be used as being a “clock” since it is unaffected by physical (e.g. temperature) and chemical ( e.g. water content) conditions. Half of the 14 C in a sample will decay (see figure 1, below) in 5,730 years.
Consequently, whenever we understand the 14 C: 12 C ratio during the time of death as well as the ratio today, we are able to determine simply how much time has passed away. Regrettably, neither are straightforward to ascertain.

The total amount of 14 C when you look at the environment, and for that reason in flowers and pets, have not been constant. As an example, the total amount differs in accordance with what amount of cosmic rays reach Earth.
