Carbon 14 dating inaccurate
This magnificent technology is the most important innovation in archaeological history.
Archaeologists have the most accurate readings they are likely to ever receive!
The technology uses a series of mathematical calculations—the most recognizable of which is known as half-life—to estimate the age the organism stopped ingesting the isotope.
Unfortunately, the amount of Carbon-14 in the atmosphere has not been steady throughout history.

Thorough research and cautiousness can eliminate accidental contamination and avoidable mistakes.
The answer to the problem of fluctuating amounts of this important isotope is calibration.
While an uncalibrated reading may be off by a factor of 10%-20%, calibration severely reduces that value.
In fact, it has fluctuated a great deal over the years.
This variation is caused by both natural processes and human activity.
