The basis for the carbon 14 dating method is that
The tiny initial amount of C14, the relatively rapid rate of decay (the half-life of C14 is currently about 5700 years) and the ease with which samples can become contaminated make radiocarbon dating results for samples "older" than about 50,000 years effectively meaningless.This limit is currently accepted by nearly all radiocarbon dating practitioners.
...[Some authors have said] they were "not aware of a single significant disagreement" on any sample that had been dated at different labs.The proton takes an electron with it and becomes an atom of hydrogen.The nitrogen atom, which began with seven protons and seven neutrons, is left with only six protons and eight neutrons.This collision is less destructive than the initial collision that produced them.Usually a proton is knocked out of the nitrogen atom's nucleus and is replaced with the neutron.is the quantity of radioactive material at time zero, X is the amount remaining after time t, and k is the first order rate constant, which is a characteristic of the isotope undergoing decay.

The normal carbon atom has six protons and six neutrons in its nucleus, giving a total atomic mass of 12.
What effect would the declining strength of the earth's magnetic field and a catastrophic worldwide flood have on radiocarbon dates?
The radioactive carbon has six protons and eight neutrons in its nucleus, giving it a total atomic mass of 14.
It uses accelerator mass spectrometry to determine the amounts of C14 and C12 in a small sample which is vaporised in the test.
The ions produced are forced into a magnetic field where the different mass of the carbon isotopes causes a different deflection, allowing the quantity of each isotope to be measured.
Radiocarbon dating is frequently used to date ancient human settlements or tools. It is a stable atom that will not change its atomic mass under normal circumstances.
