Carbon 14 radioactive dating technique

Specimens would then look much older than they actually are.d) Even if the rate of decay is constant, without knowledge of the exact ratio of carbon-12 to carbon-14in the initial sample, the dating technique is subject to question.It's assumed that the clock was set to zero when the study material was formed.This requires that only the parent isotope be initially present or that the amount of daughter isotope present at the beginning is known so that it can be subtracted.

However, conditions may have been different in the past and could have influenced the rate of decay or formation of radioactive elements.Carbon-14 comes from nitrogen and is independent of the carbon-12 reservoir.If even a small percentage of the limestone deposits were still in the form of living marine organisms at the time of the Flood, then the small amount of carbon-14 would have mixed with a much larger carbon-12 reservoir, thus resulting in a drastically reduced ratio.We could put forward the following counter arguments to the constancy of these assumptions: a) The constancy of cosmic ray bombardment might be questioned.The current high rate of entry might be a consequence of a disturbed post-Flood environment that altered the .
