Limitations carbon 14 dating objects
This method is claimed to be more accurate than the older and slower method of counting the number of radioactive decay emissions from a quite large sample.
It is the supposed accuracy of the new method that allows measurements sensitive enough to date objects claimed to be more than twenty or thirty thousand years old.
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.
Radioactive carbon (Carbon 14) is formed in the upper atmosphere as a byproduct of cosmic radiation.Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old.It is used in dating things such as bone, cloth, wood and plant fibers that were created in the relatively recent past by human activities. 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.
