This assumption is backed by numerous scientific studies and is relatively sound.However, conditions may have been different in the past and could have influenced the rate of decay or formation of radioactive elements.by Helen Fryman Question: What about radiocarbon dating? Response: I asked several people who know about this field. (1.) C14 dating is very accurate for wood used up to about 4,000 years ago.
Thus radioactive dating relies purely on assumptions.After all, this what the archeologist guessed in their published books.Some believe trees are known to be as old as 9,000 years. A lot of people doubt this claim for various good reasons I wont go into here.Scientists at the Lamont-Doherty Geological Laboratory of Columbia University at Palisades, N.
Y., reported today in the British journal Nature that some estimates of age based on carbon analyses were wrong by as much as 3,500 years.Since 1947, scientists have reckoned the ages of many old objects by measuring the amounts of radioactive carbon they contain.
