Radiocarbon dating is a well-established technique for determining the age of archaeological artifacts that were once alive. Radiocarbon or carbon-14 (14C) is naturally produced in the upper atmosphere by nuclear reactions between neutrons generated by cosmic rays and nitrogen atoms in the atmosphere.

Radiometric dating detects beta particles from the decay of carbon 14 atoms while accelerator mass spectrometry counts the number of carbon 14 atoms present in the sample. Radiometric dating via liquid scintillation counting is no longer offered by Beta Analytic, a Miami-based radiocarbon lab.

Earth sciences - Earth sciences - Radiometric dating: In 1905, shortly after the discovery of radioactivity, the American chemist Bertram Boltwood suggested that lead is one of the disintegration products of uranium, in which case the older a uranium-bearing mineral the greater should be its proportional part of lead. Analyzing specimens whose relative geologic ages were known, Boltwood found.

Radiometric dating can be performed on samples as small as a billionth of a gram using a mass spectrometer. The mass spectrometer was invented in the 1940s and began to be used in radiometric dating in the 1950s. The mass spectrometer operates by generating a beam of ionized atoms from the sample under test.

For many people, radiometric dating might be the one scientific technique that most blatantly seems to challenge the Bible’s record of recent creation. For this reason, ICR research has long focused on the science behind these dating techniques.

Having investigated the technique using flight-type planetary instrumentation, we conclude that come of the principle challenges of conducting accurate in situ radiometric dating on Mars using instruments of these types include determining the sample mass, ensuring all the argon is liberated from the sample given the maximum achievable temperature of the mass spectrometer ovens, and argon loss.

Modern Uranium-series methods use decay chains and lasers to allow dating calculations to around 500,000 years. Uranium-series (U-series) dating is another type of radiometric dating. You will remember from our consideration of C-14 dating that radiometric dating uses the known rate of decay of radioactive isotopes to date an object.

Accelerator mass spectrometry also takes less time to analyze samples for carbon 14 content compared to radiometric dating methods that ams take one or ams days. An accelerator mass spectrometer has a run thought of a few hours per sample. Lastly, it must be noted that AMS measurements usually achieve higher precision thought lower backgrounds.

The figures shown in that article are based on radiometric dating. Radiometric dating is rooted in the rates of radioactive decay of various isotopes, which rates have been measured carefully in numerous laboratories beginning in the early 20th century.. But with the advent of mass spectrometry beginning in the 1970s, even very small samples.
