### 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 radioactive dating and how does it work?

What Is Radioactive Dating, and How Does It Work? Radiometric dating (often called radioactive dating) is a technique used to date materials such as rocks or carbon, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.

### 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.

### 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.

### Can all radiometric dating methods be wrong?

In regard to the radiometric dating of rocks, it is known that various different radiometric methods often yield quite discordant dates for the same rock, thus proving that they cannot all be correct.

### 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 do scientists reject all but the oldest dating methods?

Yet when asked why they reject all but the oldest science-based dating methods, the answer often given is that (they think) long-age radiometric dating is more reliable and that science settled the matter of the earth’s age many years ago.

### Are the criticisms of young Earth creationists scientifically valid?

However, none of the criticisms of young earth creationists have any scientific merit. Radiometric dating remains a reliable scientific method. For articles on the RATE project, see the Rate Index.

### 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.

### Does radiometric dating have any scientific merit?

The topic of radiometric dating (and other dating methods) has received some of the most vicious attacks by young earth creation science theorists. However, none of the criticisms of young earth creationists have any scientific merit.

### 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.
