Radiocarbon dating work

Carbon dating is therefore only unquestionably accurate for a few thousand years; any results beyond that frame is questionable. What’s more, carbon dating seems to be based on a fallacy.It is fundamentally based on the assumption that the ratio of C-14 to C-12 atoms in the environment has always been the same throughout each and every Age. Since the Industrial Revolution, in particular, we have diluted the amount of C-12 atoms in the environment by shamelessly dumping into it an alarming quantity of carbon dioxide, produced by the burning of fossil fuels.Measuring the quantity of this radioactive carbon in organic matter allows us to determine its age; the method of doing so is called radioactive carbon dating or, simply, carbon dating. Carbon has a twin brother that only a few know about.Our planet is constantly pelted with high-energy cosmic rays hurled by the sun.These rays, which teem with neutrons, react with the nitrogen in our atmosphere to produce carbon-14 or C-14 atoms, an isotope of the carbon-12 or C-12 atom.An element and its isotope exhibit the same electric properties, but different physical properties.

The twins are then identified by different denotations, highlighting the number of neutrons, which is appended to the element’s symbol.The radioactive carbon will react with oxygen in the atmosphere to produce radioactive carbon dioxide.This radioactive carbon dioxide is breathed in and stored by plants, which are consumed by herbivores, who are preyed on by carnivores or omnivores, such as humans.This ratio is used by archaeologists to date, say, a tree or a fossil.The radioactivity of an element is measured in terms of its half-life: the time it takes to decay half of its constituents.

Again, carbon dating might not be unquestionably accurate, but it’s good enough.: Akash Peshin is an Electronic Engineer from the University of Mumbai, India and a science writer at Science ABC.
