Who uses radiocarbon dating
Radiocarbon dating is technique that uses the decay of carbon-14 to estimate the age of organic material.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 can be done at a variety of research institutions including Woods Whole and UC Irvine.Radiocarbon dating is done in labs with equipment specific to carbon 14 analysis.It follows that the older a date is, even within this 'limit', the greater are the doubts about the date's accuracy.PROBLEMS WITH RADIOCARBON DATING During the last 30 years, a new method of determining C14/C12 ratios has been developed.The method of radioactive dating used for the Turin Shroud was 'radiocarbon dating' and was invented by Willard Libby.
The carbon dioxide is absorbed by plants, and the plants are eaten by animals, thus contaminating every living thing on earth with radioactive carbon. As time passes, the C14 in its tissues is converted back into nitrogen.
Cosmic rays are positively charged atoms moving at enormous speeds.
