Scientists do not always use a 120 year range when radiocarbon dating an artifact. Calibrated radiocarbon ages are often expressed as below
2670 (± 120)
where 2670 refers to the age of the sample and the 120 after the symbol indicates that this age may be older or younger than the given age by 120 years. This varying level of precision comes in because the calibration curves used to turn radiocarbon ages into calender dates are not perfectly smooth, and it may be that for some preiods a radiocarbon age may be equivilent to serveal calender dates. This margin of error varies depending on the age of the sample and for some periods will be significantly less (maybe only a decade or so) and for some periods will be significantly more (for example during the early Iron age, 800 - 400BC where radiocarbon dating can offer no greater precision than several hundered years.
Radiocarbon dating is a widely used scientific method for determining the age of organic artifacts. By measuring the decay of carbon isotopes in a sample, scientists can determine its age within a certain range. Other methods, such as tree-ring dating and thermoluminescence dating, are also used for dating different types of artifacts.
Radiocarbon dating is generally accurate for dating organic materials up to about 50,000 years old. However, factors such as sample contamination and calibration errors can affect the accuracy of the results. It is important to consider these limitations when interpreting radiocarbon dates.
The way in which you would date an artifact would depend on several things including that material from which it was made, its value, approximately how old you think it might be, whether it is from a museum collection or an archaeological site and various other factors. There are a wide range of archaeological dating methods available to archaeologists the most well known of which is carbon dating.
Carbon dating can be used by archaeologists to estimate the age of artifacts that contain organic material. By measuring the decay of radioactive carbon isotopes in the artifact, scientists can calculate its age within a certain range. However, carbon dating is not always accurate for very old artifacts, and other dating methods may be used in conjunction with carbon dating for more precise results.
Radiocarbon dating cannot be used to date objects over 50,000 years old because after this much time has passed a large proportion of the carbon-14 has decayed and the amount remaing is too little for accurate measurement.

Radiocarbon dating is a useful technique for absolute dating within the ten thousand year range. It measures the decay of carbon-14 isotopes in organic materials, allowing scientists to determine the age of archaeological finds, fossils, and other organic remains up to about 50,000 years old. This method is particularly effective for dating materials such as wood, bone, and shell. Other techniques, like dendrochronology, can also provide precise dating within this timeframe by analyzing the growth rings of trees.
When scientists use carbon dating, the measure the amount of radioactive carbon-14 present in a fossil or organic artifact. C-14 decays at a steady rate, so if scientists can calculate the amount that has decayed, they can determine the approximate age of the artifact.
Radiocarbon dating has a higher resolution in terms of absolute dating compared to dendrochronology, as it can provide dates within a range of several decades to a few centuries. However, dendrochronology is more precise in determining the calendar years of tree-ring samples and is often considered more accurate for dating events within the past few thousand years. Both methods are valuable and are typically used together to cross-validate results.
Two basic ways are stratigraphy/provenance, and association with known artifact types (example - Clovis style points are fairly well known and described. If you find a Clovis point, you have a decent idea as to what the age range is).
Carbon dating is limited to around 50,000 years due to the half-life of the carbon-14 isotope. Once an artifact exceeds this range, there is not enough carbon-14 left to accurately measure its age. Other dating methods, such as uranium-lead dating, are used for older artifacts.
Carbon-14 conducts radiocarbon dating, meaning it determines the age of carbonaceous materials. It can determine ages of items that are up to 60,000 years old. This includes animals and plants that have died.?æ
