### How reliable is radiometric dating?

The reliability of radiometric dating is subject to three unprovable assumptions that every geologist must make when using the radioactive “clock”. Radioactive rocks offer a similar “clock.” Radioactive atoms, such as uranium (the parent isotopes), decay into stable atoms, such as lead (the daughter isotopes), at a measurable rate.

### What is a radiometric date?

Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.

### What is the most common radiometric dating method for uranium?

One common radiometric dating method is the Uranium-Lead method. This involves uranium isotopes with an atomic mass of 238. This is the most common form of uranium.

### Why is radiometric dating difficult for young Earth creationists?

Radiometric dating of rocks and minerals using naturally occurring, long-lived radioactive isotopes is troublesome for young-earth creationists because the techniques have provided overwhelming evidence of the antiquity of the earth and life.

### What are the limitations of radiometric dating?

The shortcomings of the radiometric dating method is one of many indications that our earth is only a maximum of 10,000 years old and was created by God. Another problem that calls into question the credibility of radiometric dating is heat contamination.

### What is the most common radiometric dating method?

One common radiometric dating method is the Uranium-Lead method. This involves uranium isotopes with an atomic mass of 238. This is the most common form of uranium. It decays by a 14-step process into lead-206, which is stable. Each step involves the elimination of either an alpha or a beta particle.

### Does radiometric dating prove an old Earth?

Their results consistently agree with an old Earth. Over a thousand papers on radiometric dating were published in scientifically recognized journals in the last year, and hundreds of thousands of dates have been published in the last 50 years. Essentially all of these strongly favor an old Earth.

### How do we evaluate the accuracy of radiometric ages?

We scientists who measure isotope ages do not rely entirely on the error estimates and the self-checking features of age diagnostic diagrams to evaluate the accuracy of radiometric ages. Whenever possible we design an age study to take advantage of other ways of checking the reliability of the age measurements.

### Do creationists ever find incorrect radiometric dating results?

Only rarely does a creationist actually find an incorrect radiometric result (Austin 1996; Rugg and Austin 1998) that has not already been revealed and discussed in the scientific literature. The creationist approach of focusing on examples where radiometric dating yields incorrect results is a curious one for two reasons.

### Why do radiometric dating methods give inflated ages?

We now have a good idea why most radiometric dating methods give inflated ages: there was at least one episode of accelerated radioactive decay in earth’s history. This is the only reasonable way to make sense of the abundance of helium found trapped in various rocks. The abundance of helium indicates that much radioactive decay has happened.

### How do radiometric ages agree with geologic mapping?

Third, the radiometric ages agree, within analytical error, with the relative positions of the dated ash beds as determined by the geologic mapping and the fossil assemblages; that is, the ages get older from top to bottom as they should.

### Why doesnt radiocarbon dating work on objects older than 20 thousand years?

Radiocarbon dating doesnt work well on objects much older than twenty thousand years, because such objects have so little C-14 left that their beta radiation is swamped out by the background radiation of cosmic rays and potassium-40 (K-40) decay.
