Carbon dating began
So when you compare the amount of Carbon-14 in a dead organism, with available levels in the atmosphere, you are able to make an estimate of when the organism had died.But because of the rate of decay, when all of the Carbon-14 is decayed, in about 50,000 years, it is no longer able to be carbon dated.Libby found that plants fix atmospheric carbon during photosynthesis, so the level of 14C in plants and animals when they die approximately equals the level of 14C in the atmosphere at that time.However, it decreases thereafter from radioactive decay, allowing the date of death or fixation to be estimated.Carbon-14 is a radioactive with a half life of about 5700 years.The carbon-14 forms at a rate which appears to be constant, so that by measuring the radioactive emissions from once-living matter and comparing its activity with the equilibrium of living things, a measurement of the time elapsed can be made. It is based upon the assumption that the rate of the formation of carbon 14 in the upper atmosphere is equal to the rate of decay.
Carbon 14 analysis, as in the case of other dating methods, does not really determine anything about age.
Carbon dating has been very beneficial to the scientific world, because it is used in so many different fields of science, including archaeology, geology, oceanography, hydrology, atmospheric science, and paleoclimatology.
Since technology has evolved so rapidly in the past century, we have invented new ways and other techniques to help us date non-living organisms.
Carbon dating is the most reliable, commonly used, and useful dating method, for what it can date.
When I say for what it can date, I mean it is limited to what we can actually date.
