Carbon 14 dating inaccurate

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.

These curves indicate the changes in Carbon-14 throughout the years and modifies the end result of the tests to reflect that.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.The isotope decreased by a small fraction due to the combustion of fossil fuels, among other factors.However, the quantity of Carbon-14 was nearly doubled in the ’50s and ’60s because of the atomic bomb testings in those decades.
