Problems with radiometric and carbon 14 dating creepy dating site messages
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.Cosmic rays and changes in Earth’s climate can cause irregularities in the amount of Carbon-14 in the atmosphere.
This variation is caused by both natural processes and human activity.
As the lecture detailed, it is only accurate from about 62,000 years ago to 1,200 A. There is a sizable amount of time before and after that period that cannot be investigated using this method.
Also, archaeologists cannot use their hands to touch the samples or smoke near them.
Though the calibrated date is more precise, many scholars still use the uncalibrated date in order to keep chronologies consistent in academic communities.
Though it’s biggest, the calibration problem is not the only flaw of radiocarbon dating.
This magnificent technology is the most important innovation in archaeological history.
