Radiometric dating and the age of the earth

Does radiometric dating give correct age estimates?

Radiometric dating has been demonstrated to give wrong age estimates on rocks whose age is known. Yet, secularists continue to assume that it gives correct age estimates on rocks of unknown age.

What are radioactive elements used for in radiometric dating?

In radiometric dating, the measured ratio of certain radioactive elements is used as a proxy for age. Radioactive elements are atoms that are unstable; they spontaneously change into other types of atoms. For example, potassium-40 is radioactive.

How do you determine the age of a radioactive isotope?

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.

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.

Does radiometric dating prove millions of years old?

Many accept radiometric dating methods as proof that the earth is millions of years old, in contrast to the biblical timeline. Mike Riddle exposes the unbiblical assumptions used in these calculations. The presupposition of long ages is an icon and foundational to the evolutionary model.

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 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.

What is the difference between luminescence dating and radiometric dating?

Luminescence dating methods are not radiometric dating methods in that they do not rely on abundances of isotopes to calculate age. Instead, they are a consequence of background radiation on certain minerals. Over time, ionizing radiation is absorbed by mineral grains in sediments and archaeological materials such as quartz and potassium feldspar.

How is accelerator mass spectrometry different from radiometric dating?

Accelerator mass spectrometry also takes less time to analyze samples for carbon 14 content compared to radiometric dating methods that can take one or two days. An accelerator mass spectrometer has a run time of a few hours per sample.

How does a mass spectrometer work?

The mass spectrometer was invented in the 1940s and began to be used in radiometric dating in the 1950s. It operates by generating a beam of ionized atoms from the sample under test.

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 difference between carbon dating and mass spectrometry?

Both carbon dating methods have advantages and disadvantages. Mass spectrometers detect atoms of specific elements according to their atomic weights.
