Radiometric dating clocks
By the mid-1940s, Willard Libby realized that the decay of C research—his life’s work—Libby was awarded the Nobel Prize in Chemistry in 1960, and the age of radioactive dating was born.
Before we delve into radioactive decay and its use in dating rocks, let’s review some essential nuclear physics concepts.
They were missing something absolutely fundamental. We are missing perhaps something as profound as they were back then.These radiohalos originate from tiny point-like inclusions of U or some other naturally occurring radioisotope within the crystal.Unfortunately for the secularist, there are radiohalos formed from what appears to be primordial Po (polonium), rather than Po in the form of daughter isotopes from U decay.This makes energy spectroscopy for these decays more challenging than for alpha or gamma decays.If the parent nucleus decays to an excited state of the daughter nucleus for any of the above decays, then gamma rays can also accompany the emitted particles.It is the differing number of neutrons that give rise to stable and unstable isotopes (radioisotopes) within a given elemental family.As it turns out, nearly every element from Hydrogen (Z=1) to Bismuth (Z=83) has at least one stable isotope, with Technetium (Z=43) and Promethium (Z=61) as the exceptions.The throughput rate, the rate at which the sand accumulates in the bottom chamber, is characteristic of a specific decay sequence and can be viewed as roughly analogous to the neck of the hourglass, which controls the rate at which the sand falls.(See Figure 1 below.) Secularists believe that nuclear decay has been a part of the natural world since its formation some 13.8 billion years ago, and the nuclear decay rates for the various radioisotopes have been constant throughout that time.Being knowledgeable about such a widespread dating method is essential for Christians to address opposing arguments and critics. Natural radioactivity was discovered in 1896 by the French physicist Henri Becquerel.A decade later, American chemist Bertram Boltwood suggested that lead was a disintegration product of uranium and could be used as an internal clock for dating rocks.
