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.Once the organism dies, however, it ceases to absorb carbon-14, so that the amount of the radiocarbon in its tissues steadily decreases.Carbon-14 has a half-life of 5,730 ± 40 years— during the succeeding 5,730 years.In fact, many important archaeological artifacts have been dated using this method including some of the Dead Sea Scrolls and the Shroud of Turin.Though radiocarbon dating is startlingly accurate for the most part, it has a few sizable flaws.Since trees can have a lifespan of hundreds of years, its date of death might not even be relatively close to the date the archaeologists are looking for.
Unfortunately, the amount of Carbon-14 in the atmosphere has not been steady throughout history.
Standard calibration curves are now used for more accurate readings.
These curves indicate the changes in Carbon-14 throughout the years and modifies the end result of the tests to reflect that.
Despite its overuse and misrepresentation in the media, it is nonetheless extremely valuable.
This process has seriously assisted archaeologists in their research, excavations, and scholarly studies.
