Dating techniques based on radioactive decay

Carbon-14 is also passed onto the animals that eat those plants.

After death the amount of carbon-14 in the organic specimen decreases very regularly as the molecules decay.

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.

Love-hungry teenagers and archaeologists agree: dating is hard.

Radiocarbon dating involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content.

Many examples from literature show that the zero-reset assumption is not always valid.

Volcanic ejecta of Mount Rangitoto (Auckland, New Zealand) was found to have a potassium-40 age of 485,000 years, yet trees buried within the volcanic material were dated with the carbon-14 method to be less than 300 years old.

While there is no proof that the rates were different in the past than they are today, there is also no proof that they were the same.

Thus radioactive dating relies purely on assumptions.
