For example, a team at Purdue University in Indiana was monitoring a lump of manganese-54 in a radiation detector box to measure the isotope’s half-life.At PM on December 12, 2006, the instruments recorded a sudden dip in radioactivity.So when fossils are found in sedimentary rock layers, they are identified within the context of where they fit in the evolutionary ‘tree of life’, and a millions-of-years ‘age’ is therefore assigned to the fossil and the rock accordingly.2 In recent years a variety of techniques have been developed to ‘date’ some rocks and minerals using the decay of radioactive elements in them.These methods include potassium-argon, rubidium-strontium, uranium-thorium-lead and samarium-neodymium dating.They want to know if it is accurate or if it works at all.

They all start with similar flaws, but Carbon-14 has more than the rest.The only radioactive dating method that could be directly applied to many fossils is radiocarbon or carbon-14 (C) dating.However, because radiocarbon decays relatively rapidly, it is only useful in practice up to about 50,000 years.3 Thus most fossils, being regarded as millions of years old, are never tested for radiocarbon, because they are not supposed to have any left.After ten half-lives (or 57,300 years), less than one-thousandth of the original amount remains.All life requires carbon and, chemically speaking, carbon-14 acts just like the far-more-abundant carbon-12.
