However, the quantity of Carbon-14 was nearly doubled in the ’50s and ’60s because of the atomic bomb testings in those decades.The answer to the problem of fluctuating amounts of this important isotope is calibration.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.In last Tuesday’s lecture, radiocarbon dating was covered briefly.This variation is caused by both natural processes and human activity.Cosmic rays and changes in Earth’s climate can cause irregularities in the amount of Carbon-14 in the atmosphere.

Books, clothing and food remains are all archaeological artifacts that can be carbon dated.

While an uncalibrated reading may be off by a factor of 10%-20%, calibration severely reduces that value.

Standard calibration curves are now used for more accurate readings.

Since its conception by Willard Libby in 1949, it has been invaluable to the discipline.

In fact, many important archaeological artifacts have been dated using this method including some of the Dead Sea Scrolls and the Shroud of Turin.
