Carbon Dating Method In Hindi
Because of this relatively short half-life, radiocarbon is useful for dating items of a relatively recent vintage, as far back as roughly 50,000 years before the present epoch . Radiocarbon dating cannot be used for older specimens, because so little carbon-14 remains in samples that it cannot be reliably measured .
Radiocarbon gives two options for reporting calibrated dates . A common format is "cal date-range confidence", where: date-range is the range of dates corresponding to the given confidence level; confidence indicates the confidence level for the given date range .
The overlapping nature of the tree records means this is the most accurate record we have . There will of course be several possible calendar years within the expected range , which is why radiocarbon dates come with a variation such as +/- 25 years for example (11) .

Carbon dating is thus accurate within the timeframe set by other archaeological dating techniques . Unfortunately, we aren't able to reliably date artifacts beyond several thousand years . Scientists have tried to extend confidence in the carbon dating method further back in time by calibrating the method using tree ring dating .
THE ACCURACY OF RADIOCARBON DATES BY HAROLD BARKER MORE than two decades have passed since Libby first demonstrated the existence of radioactive carbon in the atmosphere, a discovery which led to a revolutionary new method of dating past events based on measurements of the residual radioactive carbon content of materials which have once

These sequences have helped to calibrate radiocarbon dates to calendar years, thus making them more accurate . Normally after 12,500 BP, the coral dating is used . Example of calibration: 3700 ± 100 BP (P - 685) .
The point is simply this: radiometric dating is known to produce grossly erroneous dates when heat is involved in the formation or fossilization process . And since the only rocks which yield ages in excess of 100,000 years are of volcanic origin, this method of dating the earth is not based on science, but rather speculation and subjective reasoning .
Is radiocarbon dating a reliable and accurate indicator? Yes, in the same way that addition is a reliable and accurate way to add numbers together . IE: If someone doesn't carry the 2, etc, or, adds the wrong numbers, they can get a wrong answer… but the method works great .:D
Inaccurate radiocarbon dates are rarely caused by problems associated with the measurement, but are predominately the result of inadequate sample pretreatment . Over the last 35 years, numerous methods have been used to chemically purify bone, teeth, and ivory for 14 C dating by accelerator mass spectrometry (AMS) .
Many early dates were generated from bone apatite (Phillipson 2005; Sinclair 1991), which has been demonstrated as providing inaccurate radiocarbon dates in nonarid environments due to molecular exchange and fixation of carbonates from the environment to the apatite (Stafford et al . 1987; Taylor 1992) .
