In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old.At an archaeological dig, a piece of wooden tool is unearthed and the archaeologist finds it to be 5,000 years old.
When creation scientists studied granite samples, they made interesting discoveries.Much of the information presented in this section is based upon the Stuiver and Polach (1977) paper "Discussion: Reporting of C14 data". 1890 wood was chosen as the radiocarbon standard because it was growing prior to the fossil fuel effects of the industrial revolution.A copy of this paper may be found in the Radiocarbon Home Page The radiocarbon age of a sample is obtained by measurement of the residual radioactivity. T (National Institute of Standards and Technology; Gaithersburg, Maryland, USA) Oxalic Acid I (C). The activity of 1890 wood is corrected for radioactive decay to 1950.Until recent years, scientists who believe in creation haven't had the necessary resources to explore radiometric dating in detail.A 10 gram sample of U-238Now that has changed, and some important discoveries are being made.In the upper one, to find the percent of Carbon 14 remaining after a specified number of years, enter the number of years and click on Calculate.
