Carbon dating error range
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.
This half-life is very constant and will continue at the same rate forever.Table 1 shows the ideal weights necessary to achieve the level of precision (standard error) listed in Table 2.* Recommended weights given are for clean, dry material.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.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.
Taken alone, however, the carbon dating is unreliable at best, and at worst, downright inaccurate. Why not post a comment to tell others / the manufacturer and our Editor what you think. Providing the content is approved, your comment will be on screen in less than 24 hours.

All living things absorb both types of carbon; but once it dies, it will stop absorbing.
The C-12 is a very stable element and will not change form after being absorbed; however, C-14 is highly unstable and in fact will immediately begin changing after absorption.
This indicated that equilibrium had not in fact been reached, throwing off scientists’ assumptions about carbon dating. Sometimes carbon dating will agree with other evolutionary methods of age estimation, which is great.
