Carbon dating accurate reliable
Cosmic rays and changes in Earth’s climate can cause irregularities in the amount of Carbon-14 in the atmosphere.Humans began making an impact during the Industrial Revolution.
These curves indicate the changes in Carbon-14 throughout the years and modifies the end result of the tests to reflect that.Though it is not without its flaws, including several not mentioned here, it is truly an incredible creation that will be used for many years to come.In a related article on geologic ages (Ages), we presented a chart with the various geologic eras and their ages.In a separate article (Radiometric dating), we sketched in some technical detail how these dates are calculated using radiometric dating techniques.As we pointed out in these two articles, radiometric dates are based on known rates of radioactivity, a phenomenon that is rooted in fundamental laws of physics and follows simple mathematical formulas.Radiocarbon dating uses the naturally occurring isotope Carbon-14 to approximate the age of organic materials. Often, archaeologists use graves and plant remains to date sites.
Since its conception by Willard Libby in 1949, it has been invaluable to the discipline.
In last Tuesday’s lecture, radiocarbon dating was covered briefly.
It is an essential technology that is heavily involved in archaeology and should be explored in greater depth.
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.
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.
