How to solve radiometric dating questions

Uranium-Thorium-Lead Method Ages" in Billions of Years Some soil from the Moon has been dated as more than a billion years older than the uniformitarian age for the Moon.

In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years.Quick cooling or not having contact with the air can affect theoretical mechanisms for "resetting" the clock.Some times radiometric dating produces impossible results.For example, say a fossil is found that has 35% carbon 14 compared to the living sample. We can use a formula for carbon 14 dating to find the answer.Where t is the age of the fossil (or the date of death) and ln() is the natural logarithm function.Experts can compare the ratio of carbon 12 to carbon 14 in dead material to the ratio when the organism was alive to estimate the date of its death.

Radiocarbon dating can be used on samples of bone, cloth, wood and plant fibers.

To date rocks or other objects, scientists typically use radiometric dating.

In short, the ratio of radioactive and stable isotopes in the sample are determined and the measured rate at which the isotopes decay is used as an indicator of the age of the sample.

This half life is a relatively small number, which means that carbon 14 dating is not particularly helpful for very recent deaths and deaths more than 50,000 years ago.

After 5,730 years, the amount of carbon 14 left in the body is half of the original amount.

This is particularly important in light of the Biblical flood.
