Benefits of carbon 14 dating
However, there are a number of other factors that can affect the amount of carbon present in a sample and how that information is interpreted by archaeologists.
Probably the most important factor to consider when using radiocarbon dating is if external factors, whether through artificial contamination, animal disturbance, or human negligence, contributed to any errors in the determinations.if (typeof(Zen) == "undefined") Zen = ; Zen.facebook = false; Zen.developer Mode = false; Zen.notifications Enabled = true; Zen.caches Disabled = false; Confluence Admin = false; zen5 = true; zen4 = true; Zen.confluence42 = true; Zen.confluence43 = true; Zen.confluence50 = true; context = "page"; disable Edits = false; home Page Url = "/display/toxipedia/Welcome to Toxipedia"; home Page Crumb Title = "Toxipedia"; page Id = null; space Key = null; Editing = false; Zen.editing In Conf5 = Zen.confluence50 && Editing; can Edit = false; is Historical Version = false; import Word = false; can Edit Sections = false; is Licensed = true; is Blog List Placeholder = false; zen Watermark Text Transform = "$zen Watermark Text Transform"; has Draft = false; Zen.pages Collector = false; Zen.blogposts Collector = false; Zen.labels Display = false; Space Admin = false; Zen.colors.primary = to RGB("#5E3C66"); Zen.colors.secondary = to RGB("#4A823C"); Zen.colors.tertiary = to RGB("#5B80AD"); Zen.= to RGB("#49314F"); Zen.colors.medium = to RGB("#71A865"); Zen.colors.light = to RGB("#E3EDDE"); Zen.colors.darkgray = to RGB(""); Zen.colors.mediumgray = to RGB(""); Zen.colors.lightgray = to RGB(""); Zen.colors.white = to RGB(""); if (Zen.colors.primary) Zen.reverse Colors[Zen.colors.Lower Case()] = "\$zen Primary Color"; if (Zen.colors.secondary) Zen.reverse Colors[Zen.colors.Lower Case()] = "\$zen Secondary Color"; if (Zen.colors.tertiary) Zen.reverse Colors[Zen.colors.Lower Case()] = "\$zen Tertiary Color"; if (Zen.colors.dark) Zen.reverse Colors[Zen.to Lower Case()] = "\$zen Dark Color"; if (Zen.colors.medium) Zen.reverse Colors[Zen.colors.Lower Case()] = "\$zen Medium Color"; if (Zen.colors.light) Zen.reverse Colors[Zen.colors.Lower Case()] = "\$zen Light Color"; if (Zen.colors.darkgray) Zen.reverse Colors[Zen.colors.Lower Case()] = "\$zen Dark Gray Color"; if (Zen.colors.mediumgray) Zen.reverse Colors[Zen.colors.Lower Case()] = "\$zen Medium Gray Color"; if (Zen.colors.lightgray) Zen.reverse Colors[Zen.colors.Lower Case()] = "\$zen Light Gray Color"; if (Zen.colors.white) Zen.reverse Colors[Zen.colors.Lower Case()] = "\$zen White Color"; Breadcrumbs Before Collapse = 5; Site Landing Page Breadcrumb = true; Toolbar From User = false; Toolbar By Default = true; Toolbar To Anonymous Users = true; Zen.always Show Edit Buttons = false; Zen.anonymous User = true; Zen.should Open New Window For Outside Links = false; User Full Screen = false; Zen.location = ; Zen.location.images = "/plugins/servlet/zenfoundation/zenservlet/designs/brands/wanmec/images/"; Zen.location.icons = "/plugins/servlet/zenfoundation/zenservlet/designs/brands/wanmec/icons/"; Zen.quick Search Space Only = false; space Key = "wanmec"; page Id = 2818626; page Id As String = "2818626"; Blog = false ; posted Days Ago = -3164; latest Version Page Id = 2818626; page Url = "/display/wanmec/Human Health Effects"; page Title = "$Title(page)"; Title Anchor Prefix = "Human Health Effects-"; page Title Unadorned = ""; is Historical Version = false; Drafts Disabled = false; can Edit = false; can Blog = false; zen Blog Post Summary Limit = 150; Breadcrumbs = true; zen Should Show Labels = true; Stretchy = false; Zen.should Open New Window For Outside Links = true; require Label = false && !Blog && zen Should Show Labels; Edit Menu = false; Edit Header = false; Edit Footer = false; Edit Admin Notice = false; if (Edit Menu) Page Url = "/display/wanmec/menu"; if (Edit Header) Zen.header Page Url = "/display/wanmec/header"; if (Edit Footer) Zen.The introduction of "old" or "artificial" carbon into the atmosphere (i.e., the "Suess Effect" and "Atom Bomb Effect", respectively) can influence the ages of dates making them appear older or younger than they actually are.This is a major concern for bone dates where pretreatment procedures must be employed to isolate protein or a specific amino acid such as hydroxyproline (known to occur almost exclusively in bone collagen) to ensure accurate age assessments of bone specimens.Alone, or in concert, these factors can lead to inaccuracies and misinterpretations by archaeologists without proper investigation of the potential problems associated with sampling and dating.
To help resolve these issues, radiocarbon laboratories have conducted inter-laboratory comparison exercises (see for example, the August 2003 special issue of Radiocarbon), devised rigorous pretreatment procedures to remove any carbon-containing compounds unrelated to the actual sample being dated, and developed calibration methods for terrestrial and marine carbon. Radiocarbon dating can be used on either organic or inorganic carbonate materials.
Physical and chemical pretreatments are done on these materials to remove possible contaminants before they are analyzed for their radiocarbon content.
There are three principal techniques used to measure carbon 14 content of any given sample— gas proportional counting, liquid scintillation counting, and accelerator mass spectrometry.
No other scientific method has managed to revolutionize man’s understanding not only of his present but also of events that already happened thousands of years ago.
Archaeology and other human sciences use radiocarbon dating to prove or disprove theories.
In contrast to relative dating techniques whereby artifacts were simply designated as "older" or "younger" than other cultural remains based on the presence of fossils or stratigraphic position, 14C dating provided an easy and increasingly accessible way for archaeologists to construct chronologies of human behavior and examine temporal changes through time at a finer scale than what had previously been possible.
