### Does radiometric dating really work?

Scientists have concluded that it is not; it is instead a consequence of the fact that radiometric dating actually works and works quite well. Creationists who wants to dispute the conclusion that primitive meteorites, and therefore the solar system, are about 4.5 Ga old certainly have their work cut out for them!

### How does radiometric dating is used to estimate absolute age?

**Absolute** **dating** or **radiometric** **dating** is a method **used** to determine the **age** of rocks by measuring its radioactive decay. A radioactive isotope in the rock decays into a stable daughter isotope. The decay occurs at a predictable rate, so the **age** of the sample could be determined.

### 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.

### Can meteorites be dated by radiometric dating?

Some meteorites, because of their mineralogy, can be dated by more than one radiometric dating technique, which provides scientists with a powerful check of the validity of the results. The results from three meteorites are shown in Table 1.

### What is the purpose of radiometric dating?

Radiometric Dating. Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes. Different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials.

### What type of mass spectrometer is used in radiometric dating?

Thermal ionization mass spectrometer used in radiometric dating. Radiometric dating calculates an age in years for geologic materials by measuring the presence of a short-life radioactive element, e.g., carbon-14, or a long-life radioactive element plus its decay product, e.g., potassium-14/argon-40.

### Why do Geologists use radiometric decay dates?

Geologists use these dates to further define the boundaries of the geologic periods shown on the geologic time scale. Radiometric decay occurs when the nucleus of a radioactive atom spontaneously transforms into an atomic nucleus of a different, more stable isotope.

### How is radiometric research used in paleontology?

But radiometric methods are also used heavily in day-to-day research in paleontology and evolutionary biology, in order to test certain hypotheses.
