Carbon dating for children

At an ar­chaeological dig, a piece of wooden tool is unearthed and the archaeologist finds it to be 5,000 years old.A child mummy is found high in the Andes and the archaeologist says the child lived more than 2,000 years ago.It has been summed up most succinctly in the words of American neuroscience Professor Bruce Brew: that samples of moss could be brought back to life after being frozen in ice. That carbon dating deemed the moss to have been frozen for over 1,500 years.Now, if this carbon dating agrees with other evolutionary methods of determining age, the team could have a real discovery on their hands.Since the universe is estimated to be millions of years old, it was assumed that this equilibrium had already been reached.However, in the 1960s, the growth rate was found to be significantly higher than the decay rate; almost a third in fact.All living things absorb both types of carbon; but once it dies, it will stop absorbing.

This rate of decay, thankfully, is constant, and can be easily measured in terms of ‘half-life’.

Specifically, there are two types of carbon found in organic materials: carbon 12 (C-12) and carbon 14 (C-14).

It is imperative to remember that the material must have been alive at one point to absorb the carbon, meaning that carbon dating of rocks or other inorganic objects is nothing more than inaccurate guesswork.

However, a little more knowledge about the exact ins and outs of carbon dating reveals that perhaps it is not quite as fool-proof a process as we may have been led to believe.

At its most basic level, carbon dating is the method of determining the age of organic material by measuring the levels of carbon found in it.
