Also, the larger the sample the better, although new techniques mean smaller samples can sometimes be tested more effectively.The person who wrote these words lived in the 1800s, many years before archaeologists could accurately date materials from archaeological sites using scientific methods.Rasmus Nyerup's quote reminds us of the tremendous scientific advances which have taken place in the 20th century.Archaeologists can then measure the amount of carbon-14 compared to the stable isotope carbon-12 and determine how old an item is.For the most part, radiocarbon dating has made a huge difference for archaeologists everywhere, but the process does have a few flaws.The half-life of a radioactive isotope (usually denoted by \(t_\)) is a more familiar concept than \(k\) for radioactivity, so although Equation \(\ref\) is expressed in terms of \(k\), it is more usual to quote the value of \(t_\).
