Libby, who received the Nobel Prize. ... There are some problems affecting the accuracy of carbon dating such as destruction of a tiny part of manuscript, …The accuracy of carbon dating decreases as the age of the object increases, with an effective range of around 50,000 years. The presence of contaminants or environmental factors can alter the amount of carbon-14 in a sample, potentially leading to inaccurate results.Carbon dating is reliable within certain parameters but certainly not infallible. First, carbon dating only works on matter that was once alive, and it only determines the approximate date of death for that sample.

There is no exact date beyond which carbon 14 decay is/is not useful. However, given that the half life of carbon 14 is 5730 years, then there really isn't much carbon 14 left in a sample that is 60,000 years old. The decay constant is λ = ln 2/t1/2 λ = ln 2 / t 1 / 2, so the fraction of carbon left would be exp[−λt] exp [ − ...

Carbon-14 Dating Carbon- 4 ( 4C), also referred to as radiocar-bon, is claimed to be a reliable dating method for determining the age of fossils up to 50,000 to 60,000 years. If this claim is true, the biblical account of a young earth (about 6,000 years) is in question, since 4C dates of tens of thousands of years are common. It's used to determine the age of organic materials (e.g. wood, charcoal, and bone) by measuring the amount of the radioactive isotope, carbon-14, remaining in the sample.

The 14 C dating approach using water-insoluble organic carbon (WIOC) from glacier ice has become a well-established technique for ice core dating, and its accuracy was recently validated (Uglietti et al., 2016). Ice samples from mid- and low-latitude glaciers can now be dated with a reasonable uncertainty of 10 %–20 %.Libby himself. "...
