The Problems with Carbon Dating. By Contender Ministries: Carbon dating is the standard method used by scientists to determine the age of certain fossilized remains. As scientists will often claim something to be millions or billions of years old (ages that do not conform to the Biblical account of the age of the earth), Christians are.
They have their work cut out for them, however, because radiocarbon (C) dating is one of the most reliable of all the radiometric dating methods. This article will answer several of the most common creationist attacks on carbon dating, using the question-answer format that has proved so useful to lecturers and debaters.
Dec 09, · C14 dating is very accurate for wood used up to about 4, years ago. This is only because it is well calibrated with objects of known age. Example: wood found in a grave of known age by historically reliable documents is the standard for that time for the C14 content.

Carbon 14 Dating Problem Carbon 14 is an isotope of carbon that is formed when radiation from the Sun strikes ordinary carbon dioxide in the atmosphere. Plants such as trees, which get their carbon dioxide from the atmosphere, therefore contain small amounts of carbon
Task. In order to use Carbon $14$ for dating, scientists measure the ratio of Carbon $14$ to Carbon $12$ in the artifact or remains to be dated. When an organism dies, it ceases to absorb Carbon $14$ from the atmosphere and the Carbon $14$ within the organism decays exponentially, becoming Nitrogen $14$, with a half-life of approximately $$ years.
Remains containing 14% of the original amount of Carbon are found. Knowing that Carbon half-live is τ = years, date the remains. Solution: Set t = 0 when the organism dies. Since the amount N of Carbon only decays after the organism dies, N(t) = N 0 2−t/τ, τ = years. The remains contain 14% of the original amount at the time t, N(t) N 0.
