Question: "Is carbon dating a reliable method for determining the age of things? Several factors affect radiocarbon test results, not all of which are easy to control objectively. Carbon dating is reliable within certain parameters but certainly not infallible. When testing an object using radiocarbon dating, several factors have to be considered: First, carbon dating only works on matter that was once alive, and it only determines the approximate date of death for that sample. For example, a steel spearhead cannot be carbon dated, so archaeologists might perform testing on the wooden shaft it was attached to. This provides good information, but it only indicates how long ago that piece of wood was cut from a living tree.
Gas proportional counting is a conventional radiometric dating technique that counts the beta particles emitted by a given sample. Beta particles are products of radiocarbon decay. In this method, the carbon sample is first converted to carbon dioxide gas before measurement in gas proportional counters takes place.
Creation v. Evolution: How Carbon Dating Works
Liquid scintillation counting is another radiocarbon dating technique that was popular in the s. In this method, the sample is in liquid form and a scintillator is added. This scintillator produces a flash of light when it interacts with a beta particle.
A vial with a sample is passed between two photomultipliers, and only when both devices register the flash of light that a count is made.
Accelerator mass spectrometry AMS is a modern radiocarbon dating method that is considered to be the more efficient way to measure radiocarbon content of a sample. In this method, the carbon 14 content is directly measured relative to the carbon 12 and carbon 13 present.
The method does not count beta particles but the number of carbon atoms present in the sample and the proportion of the isotopes. Not all materials can be radiocarbon dated. Most, if not all, organic compounds can be dated.

Samples that have been radiocarbon dated since the inception of the method include charcoalwoo twigs, seedsbonesshellsleatherpeatlake mud, soilhair, potterypollenwall paintings, corals, blood residues, fabricspaper or parchment, resins, and wateramong others.
Physical and chemical pretreatments are done on these materials to remove possible contaminants before they are analyzed for their radiocarbon content. The radiocarbon age of a certain sample of unknown age can be determined by measuring its carbon 14 content and comparing the result to the carbon 14 activity in modern and background samples. The principal modern standard used by radiocarbon dating labs was the Oxalic Acid I obtained from the National Institute of Standards and Technology in Maryland.
Minimum age for carbon dating
This oxalic acid came from sugar beets in When the stocks of Oxalic Acid I were almost fully consumed, another standard was made from a crop of French beet molasses. Over the years, other secondary radiocarbon standards have been made.
Radiocarbon activity of materials in the background is also determined to remove its contribution from results obtained during a sample analysis. Background samples analyzed are usually geological in origin of infinite age such as coal, lignite, and limestone.
A radiocarbon measurement is termed a conventional radiocarbon age CRA. The CRA conventions include a usage of the Libby half-life, b usage of Oxalic Acid I or II or any appropriate secondary standard as the modern radiocarbon standard, c correction for sample isotopic fractionation to a normalized or base value of These values have been derived through statistical means.
American physical chemist Willard Libby led a team of scientists in the post World War II era to develop a method that measures radiocarbon activity.
Apr 01, It is confusing when the maximum date for Carbon 14 is listed as 60, years and 80, years in the same article (Chapter 4 Dating Methods by Roger Patterson and the reference article summary by Riddle.) and as 50, years in another (The Answers Book) as well as 95, years in the Creation College lecture by Dr. Andrew thefoodlumscatering.com: Dr. Andrew A. Snelling. Carbon dating is used now for almost everything old that people want to date. It is taken as fact and used as evidence to gather information on the world and past civilizations. However, Carbon dating is at best a good theory, and that is all it is, a theory. Too many people forget the definition of .

With carbon dating, what is the most recent date which can be accurately determined, and why?. Is there an accepted time range, within which, accurate results can be attained using carbon dating? I understand that the method can provide dating up to ca. 50, years into the past, but I'm interested in the other end of the time range: is there a point in time when . Jan 02, Question: "Is carbon dating a reliable method for determining the age of things?" Answer: Carbon dating, or radiocarbon dating, like any other laboratory testing technique, can be extremely reliable, so long as all of the variables involved are controlled and understood. Several factors affect radiocarbon test results, not all of which are easy to control objectively. What is the acceptable minimum age for a dating partner? When this question comes up in conversation, someone inevitably cites the half your age .
