All methods of radioactive dating rely on three assumptions that may not necessarily be true: It is assumed that the rate of decay has remained constant over time.

That is until careful measurements revealed a significant disequalibrium. All the present C-14 would accumulate, at present rates of production and build up, in less than 30,000 years!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.Thus the earth's atmosphere couldn't be any older than this.Efforts to salvage carbon dating are many and varied, with calibration curves attempting to bring the C-14 "dates" in line with historical dates, but these produce predictably unreliable results.
