Radiometric dating is a much misunderstood phenomenon to understand what exactly is being measured during a radiometric dating test it is for this reason that creationists question radiometric dating methods and do. Thus, the necessary assumptions on which the radioactive “clocks” for the dating of rocks are based are unprovable no geologists were there to test these clocks in the past, but they have been demonstrated, even by secular geologists, to be plagued with problems rocks may have inherited parent and. 5) to use radiometric dating and the principles of determining relative age to show how ages of rocks and fossils can be narrowed even if they cannot be dated.
Scientists combine several well-tested techniques to find out the ages of fossils the most important are relative dating, in which fossils and layers of rock are placed in order from older to younger, and radiometric dating, which allows the actual ages of certain types of rock to be calculated relative dating fossils are. Dating can now be performed on samples as small as a nanogram using a mass spectrometer 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 the ions then travel through a magnetic.
